cmath – mathematical functions for complex numbers¶
This module implements a subset of the corresponding CPython module,
as described below. For more information, refer to the original
CPython documentation: cmath.
The cmath module provides some basic mathematical functions for
working with complex numbers.
Availability: not available on WiPy and ESP8266. Floating point support required for this module.
Functions¶
- cmath.cos(z)¶
Return the cosine of
z.
- cmath.exp(z)¶
Return the exponential of
z.
- cmath.log(z)¶
Return the natural logarithm of
z. The branch cut is along the negative real axis.
- cmath.log10(z)¶
Return the base-10 logarithm of
z. The branch cut is along the negative real axis.
- cmath.phase(z)¶
Returns the phase of the number
z, in the range (-pi, +pi].
- cmath.polar(z)¶
Returns, as a tuple, the polar form of
z.
- cmath.rect(r, phi)¶
Returns the complex number with modulus
rand phasephi.
- cmath.sin(z)¶
Return the sine of
z.
- cmath.sqrt(z)¶
Return the square-root of
z.
