cmath – 复数的数学函数¶
警告
待实现。
|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
rand phasephi.
-
cmath.sin(z)¶ Return the sine of
z.
-
cmath.sqrt(z)¶ Return the square-root of
z.
