Python cmath - exp() Function
The Python cmath.exp() function returns base-e exponential of a complex number z, that is e (Euler's number, 2.7182818) raised to the power of z, ez. It is a function on complex plane, and has no branch cuts.
Mathematically, it can be expressed as:
where, z = x+iy
Syntax
cmath.exp(z)
Parameters
z |
Required. Specify the exponent of e. |
Return Value
Returns e raised to the power of z.
Example:
In the example below, exp() function is used to calculate e raised to the power of specified complex number.
import cmath
z1 = 2 + 2j
z2 = 2
z3 = 2j
print("cmath.exp(z1):", cmath.exp(z1))
print("cmath.exp(z2):", cmath.exp(z2))
print("cmath.exp(z3):", cmath.exp(z3))
The output of the above code will be:
cmath.exp(z1): (-3.074932320639359+6.71884969742825j) cmath.exp(z2): (7.38905609893065+0j) cmath.exp(z3): (-0.4161468365471424+0.9092974268256817j)
