# Using Math log10() function to coding in Javascript/JS

This JavaScript tutorial explains how to use the math characteristic called log10() with syntax and examples.

## Description

In JavaScript, log10() is a function that is used to return the base-10 logarithm of a number. Because the log10() function is a static characteristic of the Math object, it must be invoked thru the placeholder object referred to as Math.

## Syntax

In JavaScript, the syntax for the log10() function is:

``Math.log10(number);``

Parameters or Arguments

number The variety to use in the calculation. It need to be a price that is greater than zero

## Returns

The log10() characteristic returns the base-10 logarithm of a number.

If the wide variety is 0, the log10() function will return -Infinity.

If the number is a poor value, the log10() function will return NaN.

## Note

Math is a placeholder object that includes mathematical functions and constants of which log10() is one of these functions.

## Example

Let’s take a seem to be at an example of how to use the log10() function in JavaScript.

For example:

``````console.log(Math.log10(1));
console.log(Math.log10(2.5));
console.log(Math.log10(0));
console.log(Math.log10(-4));``````

In this example, we have invoked the log10() characteristic the usage of the Math class.

We have written the output of the log10() function to the web browser console log, for demonstration purposes, to exhibit what the log10() characteristic returns.

The following will be output to the net browser console log:

``````0
0.3979400086720376
-Infinity
NaN``````

In this example, the first output to the console log again zero which is the base-10 logarithm of 1.

The 2d output to the console log returned 0.3979400086720376 which is the base-10 logarithm of 2.5.

The 2nd output to the console log lower back -Infinity due to the fact that the variety provided was zero

The 2d output to the console log lower back NaN seeing that the quantity supplied was once a poor value.
