cmath
– 用于复数的数学函数
¶
This module implements a subset of the corresponding
CPython
module, as described below. For more information, refer to the original CPython documentation:
cmath
.
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.
函数 ¶
-
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 ) ¶ -
