Syntax
Parameters
x-
A number greater than or equal to 0.
Return value
The base 10 logarithm of x. If x < 0, returns NaN.
Description
Because log10() is a static method of Math, you always use it as Math.log10(), rather than as a method of a Math object you created (Math is not a constructor).
This function is the equivalent of Math.log(x) / Math.log(10). For log10(e), use the constant Math.LOG10E, which is 1 / Math.LN10.
Examples
Using Math.log10()
js
Math.log10(-2); // NaN
Math.log10(-0); // -Infinity
Math.log10(0); // -Infinity
Math.log10(1); // 0
Math.log10(2); // 0.3010299956639812
Math.log10(100000); // 5
Math.log10(Infinity); // Infinity
