Imaginary class

Represents an imaginary number, defined as a number whose square is negative one.

An imaginary number is usually displayed as a value followed by small letter 'i'. 'i' squared is defined as -1 (or equivalently, the square root of -1 is defined as 'i').

Properties

complexArgument → num

The complex argument, or phase, of this imaginary number in radians.

no setter

complexModulus → Number

The complex modulus is the absolute value of this Imaginary number.

no setter

hashCode → int

The hash codes for two Numbers will be equal when the represented values are equal, even if the Number subtypes are different.

no setter, override

isFinite → bool

Whether this Number represents a finite value.

no setter, inherited

isInfinite → bool

Always returns false as the value in the real dimension is 0. To find whether the imaginary component is infinite use value.isInfinite.

no setter, override

isInteger → bool

Always returns true as the value in the real dimension is 0. To find whether the imaginary component is an integer use value.isInteger.

no setter, override

isNaN → bool

Always returns false as the value in the real dimension is 0. To find whether the imaginary component is NaN use value.isNaN.

no setter, override

isNegative → bool

Always returns false as the value in the real dimension is 0. To find whether the imaginary component is negative use value.isNegative.

no setter, override

phase → num

The phase is synonymous with the complex argument.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

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 setter, inherited

value → Real

The value of the imaginary component as a Real number.

final

Methods

abs() → Number

The absolute value of a Complex number is its distance from zero in the Complex number space (e.g., the absolute value of 0 + 4i = 4). The absolute value is always a real number.

override

ceil() → Number

The integer ceiling of a purely imaginary number is always zero.

override

clamp(dynamic lowerLimit, dynamic upperLimit) → Number

Clamps the real portion of a complex number having this imaginary value.

override

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

floor() → Number

The integer floor of a purely imaginary number is always zero.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reciprocal() → Number

Returns the Number that is the reciprocal of this Number. This Number is unaffected.

override

remainder(dynamic divisor) → Number

The real remainder will always be zero.

override

round() → Number

The nearest integer of a purely imaginary number is always zero.

override

toComplex() → Complex

Returns a Complex number equivalent to this Imaginary number.

toDouble() → double

Always returns zero.

override

toInt() → int

Always returns zero.

override

toJson() → Map<String, dynamic>

Support dart:convert json.

override

toString() → String

A string representation of this object.

override

truncate() → Number

The integer resulting from truncation of a purely imaginary number is always zero.

override

Operators

operator %(dynamic divisor) → Number

The modulo operator (not supported).

override

operator *(dynamic multiplicand) → Number

Returns the product of this Number and the multiplicand (a Number or num). This Number is unaffected.

override

operator +(dynamic addend) → Number

Returns the sum of this Number and a Number or num. This Number is unaffected.

override

operator -(dynamic subtrahend) → Number

Returns the difference of this Number and the subtrahend (a Number or num). This Number is unaffected.

override

operator /(dynamic divisor) → Number

Returns the quotient of this Number divided by the divisor (a Number or num). This Number is unaffected.

override

operator <(dynamic obj) → bool

Returns whether the value of this Number is less than the value of obj (a Number or num).

override

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).

override

operator ==(Object obj) → bool

Two Numbers will be equal when the represented values are equal, even if the Number subtypes are different.

override

operator >(dynamic obj) → bool

If obj is an Imaginary number then the comparison is made in the imaginary dimension (for example, 5i > 3i is true).

override

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).

override

operator ^(dynamic exponent) → Number

The power operator (note: NOT bitwise XOR).

override

operator unary-() → Imaginary

Returns the negative of this Number. This Number is unaffected.

override

operator ~/(dynamic divisor) → Number

The truncating division operator.
