Python Number Log10() Method



The log10() method in Python number returns the base-10 logarithm of x for the values of x > 0. The Python log10 function is yet another function of Python Math \responsible for calculating the logarithmic value of a specific number with base 10. When compared to math.log(x, 10) the Python log10 function comes out to be more accurate.


Following is the syntax for log10() method:

import math

math.log10( x )

Note - This function is not accessible directly, so we need to import the math module, and then we need to call this function using a math static object.


  • x - This is a numeric expression.

Return Value

This method returns base-10 logarithm of x for x > 0.


The following example shows the usage of log10() metho

import math   # This will import math module

print "math.log10(100.12) : ", math.log10(100.12)
print "math.log10(100.72) : ", math.log10(100.72)
print "math.log10(119L) : ", math.log10(119L)
print "math.log10(math.pi) : ", math.log10(math.pi)

When we run the above program, it produces the following result:

math.log10(100.12) :  2.00052084094
math.log10(100.72) :  2.0031157171
math.log10(119L) :  2.07554696139
math.log10(math.pi) :  0.497149872694
