Translatecmath – mathematical functions for complex numbers
This module implements a subset of the corresponding CPython module, as described below. For more information, please refer to the original CPython documentation: cmath.
The cmath module provides some basic mathematical functions for dealing with complex numbers.
Function
cos
cmath.cos(z)Returns the cosine of z.
exp
cmath.exp(z)Returns the exponent of z.
log
cmath.log(z)Returns the natural logarithm of z. The branch cuts along the negative real axis.
log10
cmath.log10(z)Returns the base 10 logarithm of z. The branch cuts along the negative real axis.
phase
cmath.phase(z)Returns the phase, range (-pi, +pi) of the number "z".
polar
cmath.polar(z)Return the polar form of z as a tuple.
rect
cmath.rect(r, phi)Returns the complex number of the modulus r and the phase phi.
sin
cmath.sin(z)Returns the sine of z.
sqrt
cmath.sqrt(z)Returns the square root of z.
Constants
cmath.e
The basis of natural logarithm
cmath.pi
Ratio of circumference to diameter
