## Description

The log10() method returns base-10 logarithm of x for x > 0.

## Syntax

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 the math static object.

## Parameters

x − This is a numeric expression.

## Return Value

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

## Example

The following example shows the usage of the log10() method.

```#!/usr/bin/python3
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(119) : ", math.log10(119))
print ("math.log10(math.pi) : ", math.log10(math.pi))
```

## Output

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

```math.log10(100.12) :  2.0005208409361854
math.log10(100.72) :  2.003115717099806
math.log10(119) :  2.0755469613925306
math.log10(math.pi) :  0.49714987269413385
