Properties

hashCode → int

Returns a hash code for a numerical value.

no setter, override

isInfinite → bool

True if the number is infinite; otherwise, false.

no setter, override

isNaN → bool

True if the number is not a number; otherwise, false.

no setter, override

isNegative → bool

True if the number is negative; otherwise, false.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sign → Integer

Returns minus one, zero or plus one depending on the sign and numerical value of the number.

no setter, override

value ↔ int

getter/setter pair

Methods

abs() → Number

Returns the absolute value of this num.

override

ceil() → Integer

Returns the least integer no smaller than this.

override

compareTo(Number other) → int

Compares this to other.

override

floor() → Integer

Returns the greatest integer no greater than this.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

remainder(Number other) → Number

Returns the remainder of the truncating division of this by other.

override

round() → Integer

Returns the integer closest to this.

override

roundWithPrecision(int precision, [RoundingMode mode = RoundingMode.nearestEven]) → Number

Returns number rounded according to precision and RoundingMode.

override

toInt() → int

Truncates this Number to an integer and returns the result as an int. */

override

toInteger() → Integer

Truncates this Number to an integer and returns the result as an Integer.

override

toString() → String

Returns the shortest string that correctly represent the input number.

override

toStringAsExponential([int? fractionDigits]) → String

Returns an exponential string-representation of this.

override

toStringAsFixed(int fractionDigits) → String

Returns a decimal-point string-representation of this. Converts this to a Decimal before computing the string representation. If the absolute value of this is greater or equal to 10^21 then this methods returns an exponential representation computed by this.toStringAsExponential(). Otherwise the result is the closest string representation with exactly fractionDigits digits after the decimal point. If fractionDigits equals 0 then the decimal point is omitted.

override

toStringAsPrecision(int precision) → String

Converts this to a decimal and returns a string representation with exactly precision significant digits.

override

truncate() → Integer

Returns the integer obtained by discarding any fractional digits from this.

override

Operators

operator %(Number other) → Number

Euclidean modulo operator.

override

operator *(Number other) → Number

Multiplication operator.

override

operator +(Number other) → Number

Addition operator.

override

operator -(Number other) → Number

Subtraction operator.

override

operator /(Number other) → Decimal

Division operator.

override

operator <(Number other) → bool

Relational less than operator.

override

operator <=(Number other) → bool

Relational less than or equal operator.

override

operator ==(Object other) → bool

Test whether this value is numerically equal to other.

override

operator >(Number other) → bool

Relational greater than operator.

override

operator >=(Number other) → bool

Relational greater than or equal operator.

override

operator unary-() → Number

Negate operator.

override

operator ~/(Number other) → Integer

Truncating division operator.
