cmath
– mathematical functions for complex numbers
|see_cpython_module| python: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
r
and phasephi
.
- cmath.sin(z)
Return the sine of
z
.
- cmath.sqrt(z)
Return the square-root of
z
.
