A representation of a complex number, i.e. a number which has both a real and imaginary part.

Complex

A representation of a complex number, i.e. a number which has both a real and an imaginary part.

Translated from The Apache Commons Mathematics Library into Dart.

Implementations of arithmetic operations handle NaN and infinite values according to the rules for double, i.e. == is an equivalence relation for all instances that have a NaN in either real or imaginary part, e.g. the following are considered equal:

• 1 + NaNi
• NaN + i
• NaN + NaNi

Note that this is in contradiction with the IEEE-754 standard for floating point numbers (according to which the test x == x must fail if x is NaN).

Example

const z1 = Complex(1);
const z2 = Complex(3, 4);
print(z1.abs()); // 1.0
print(z2.abs()); // 5.0
print(z2.conjugate()); // (3.0, -4.0)
