Constructors

Hexadecimal.new(String hexStr)
Constructs a instance.

Properties

hashCode → int
Returns the same hash as the int with the same value.
no setterinherited
isFinite → bool
Whether this Number represents a finite value.
no setterinherited
isInfinite → bool
Whether this Number represents infinity.
no setterinherited
isInteger → bool
True if the Number represents an integer value. Note that the Number does not have to be of type Integer for this to be true.
no setterinherited
isNaN → bool
Whether this Number represents a value .
no setterinherited
isNegative → bool
Whether this number is less than zero.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sign → num
Returns minus one, zero or plus one depending on the sign and numerical value of the number. Returns minus one if the number is less than zero, plus one if the number is greater than zero, and zero if the number is equal to zero. Returns NaN if the number is NaN. Returns an int if this Number's value is an integer, a double otherwise.
no setterinherited
value → int
All Real subclasses must be able to provide their value as a dart:core num.
no setterinherited

Methods

abs() → Integer
The absolute value, returned as an Integer. Returns itself if its value is greater than or equal to zero.
inherited
asFraction() → Fraction
Returns the fractional type of the value
inherited
bitwiseXor(dynamic n) → Integer
A substitute method to perform bitwise XOR operation on integers. The caret operator is overridden to provide a power operator for all Numbers.
inherited
ceil() → Number
Returns the least Number having integer components no smaller than this Number.
inherited
clamp(dynamic lowerLimit, dynamic upperLimit) → Number
Returns this num clamped to be in the range lowerLimit-upperLimit. The comparison is done using compareTo and therefore takes -0.0 into account. This also implies that double.NAN is treated as the maximal double value. lowerLimit and upperLimit are expected to be num or `Number' objects.
inherited
compareTo(dynamic n2) → int
Compares this Number to another Number by comparing values. n2 is expected to be a num or Number. If it is not it will be considered to have a value of 0.
inherited
exp() → Number
Returns the natural exponentiation of a number.
inherited
floor() → Number
Returns the greatest Number with an integer value no greater than this Number. If this is not finite (NaN or infinity), throws an UnsupportedError.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
nthRoot(double nth, {bool allRoots = false}) → dynamic
Get the nth root of the number
inherited
pow(num exponent) → Number
Find the square root of the number
inherited
reciprocal() → Number
Returns the Number that is the reciprocal of this Number. This Number is unaffected.
inherited
remainder(dynamic divisor) → Number
Returns the remainder of the truncating division of this Number by divisor. The result r of this operation satisfies: this == (this ~/ other) * other + r. As a consequence the remainder r has the same sign as the operator /(divisor).
inherited
round() → Number
Returns the integer Number closest to this Number. Rounds away from zero when there is no closest integer: (3.5).round() == 4 and (-3.5).round() == -4. If this is not finite (NaN or infinity), throws an UnsupportedError.
inherited
roundTo([int decimalPlaces = 0]) → Number
This method shifts the decimal point decimalPlaces places to the right, rounds to the nearest integer, and then shifts the decimal point back to the left by the same amount. The default value of decimalPlaces is 0.
inherited
sqrt() → Number
Find the square root of the number
inherited
toDouble() → double
Converts this Number to a dart:core double.
inherited
toFraction([int precision = 64]) → List<int>
Approximates the double as a simple fraction with the numerator and denominator as elements of a list. Example:
inherited
toFractionString() → String
Returns a string representation of the double as a simple fraction. Example:
inherited
toInt() → int
Converts this Number to a dart:core int.
inherited
toJson() → Map<String, int>
Support dart:json stringify.
inherited
toMixedFraction() → List<int>
Converts the double to a mixed fraction represented as a list of integers where the first element is the whole number, the second is the numerator of the fractional part, and the third is the denominator of the fractional part. Example:
inherited
toMixedFractionString() → String
Returns a string representation of the double as a mixed fraction. Example:
inherited
toString() → String
A string representation of this object.
override
toWords({String lang = 'en', String? conjunction, Currency? currency, int decimalPlaces = 2, bool useOrdinal = false}) → String

Available on Number, provided by the NumberToWordsExtension extension

truncate() → Number
Returns a truncated value.
inherited

Operators

operator %(dynamic divisor) → Number
The modulo operator.
inherited
operator &(dynamic n) → Number
Bitwise AND.
inherited
operator *(dynamic multiplicand) → Number
Returns the product of this Number and the multiplicand (a Number or num). This Number is unaffected.
inherited
operator +(dynamic addend) → Number
Addition operator.
inherited
operator -(dynamic subtrahend) → Number
Returns the difference of this Number and the subtrahend (a Number or num). This Number is unaffected.
inherited
operator /(dynamic divisor) → Number
Returns the quotient of this Number divided by the divisor (a Number or num). This Number is unaffected.
inherited
operator <(dynamic obj) → bool
Returns whether the value of this Number is less than the value of obj (a Number or num).
inherited
operator <<(dynamic n) → Number
Shift the bits of this integer to the left by n.
inherited
operator <=(dynamic obj) → bool
Returns whether the value of this Number is less than or equal to the value of obj (a Number or num).
inherited
operator ==(dynamic obj) → bool
Tests whether this Integer is equal to another Object obj. Only num and Number objects having the same real integer value (and no imaginary component) are considered equal.
inherited
operator >(dynamic obj) → bool
Returns whether the value of this Number is greater than the value of obj (a Number or num).
inherited
operator >=(dynamic obj) → bool
Returns whether the value of this Number is greater than or equal to the value of obj (a Number or num).
inherited
operator >>(dynamic n) → Number
Shift the bits of this integer to the right by n.
inherited
operator ^(dynamic exponent) → Number
The power operator (note: NOT bitwise XOR).
inherited
operator unary-() → Integer
Negation operator.
inherited
operator |(dynamic n) → Number
Bitwise OR.
inherited
operator ~() → Integer
The bit-wise negate operator.
inherited
operator ~/(dynamic divisor) → Number
The truncating division operator. When dividing by an Imaginary or Complex number, the result will contain an imaginary component. The imaginary component is not truncated; only the real portion of the result is truncated.
