Python cmath.log10() Method

❮ cmath Methods

Example

Find the base-10 logarithm of a complex number:

#Import cmath Library
import cmath

#print base-10 log value of complex numbers
print (cmath.log10(2+ 3j))
print (cmath.log10(1+ 2j))
Try it Yourself »

Definition and Usage

The cmath.log10() method returns the base-10 logarithm of a complex number.

There is one branch cut, from 0 along the negative real axis to -∞, continuous from above.

Syntax

cmath.log10(x)

Parameter Values

Parameter Description
x Required. Specifies the value to calculate the base-10 logarithm for. If the value is 0 or a negative number, it returns a ValueError. If the value is not a number, it returns a TypeError

Technical Details

Return Value: A complex value, representing the base-10 logarithm of a number
Python Version: 1.5
