WebApr 10, 2024 · In Python, cmath.exp() is a method in the cmath module that returns the exponential of a complex number. The syntax for cmath.exp(z) is as follows:. import cmath result = cmath.exp(z) Here, z is the complex number whose exponential we want to calculate, and result is the value of the exponential of z. The exponential of a complex … WebThe cmath.exp() method accepts a complex number and returns the exponential value. If the number is x, it returns e**x where e is the base of natural logarithms. Syntax. …
WebJun 30, 2024 · The cmath module provides two power functions namely exp() and sqrt() for calculations in python. The exp() function takes a complex number as input and returns a complex number representing the exponential value of the input. This can be seen in the following example. WebJul 18, 2005 · So why not math.exp(complex)? Use the cmath module for complex ops: Thanks, but then my next question is, why are math and cmath different from each other? And, is there any important difference (e.g. in numerical accuracy) between cmath.exp(x) and math.e**x ?--
