A package provides implementation of complex numbers and some mathematical functions for complex numbers.

The Complex class represents a complex number which has a real part and an imaginary part. It is expressed in form a + bi, where:

• a: the real part
• b: the imaginary part
• i: the imaginary unit

You can also create a complex number using cmplx function.

import { cmplx } from "@babia/complex";

const cmplx1 = cmplx(1, 9); // 1 + 9i
const cmplx2 = cmplx(5, 4); // 5 + 4i

The Complex class has methods to perform basic operations, such as add(), sub(), etc.

import { cmplx } from "@babia/complex";

const cmplx1 = cmplx(1, 9); // 1 + 9i
const cmplx2 = cmplx(5, 4); // 5 + 4i

cmplx1.add(cmplx2); // (1 + 9i) + (5 + 4i)
cmplx1.sub(cmplx2); // (1 + 9i) - (5 + 4i)

Besides that, this package also has ComplexMath which provides basic mathematics functionality for complex numbers, such as sin(), atan(), log(), etc.

import { ComplexMath, cmplx } from "@babia/complex";

const cmplx1 = cmplx(1, 9); // 1 + 9i
const cmplx2 = cmplx(5, 4); // 5 + 4i

ComplexMath.sqrt(cmplx1);
ComplexMath.log(cmplx1);
ComplexMath.pow(cmplx2, 3);
