Arithmetic-related operations

Just as we discussed earlier, JavaScript also exposes some functions to perform logarithmic and exponential calculations, which are quite handy in a lot of situations (especially when you're creating games).

The following example code, which shows all arithmetic-related methods added to the Math object:

console.log(Math.log2(16)); //log base 2console.log(Math.log10(1000)); //log base 10console.log(Math.log1p(0)); //same as log(1 + value)console.log(Math.expm1(0)); //inverse of Math.log1p()console.log(Math.cbrt(8)); //cube root of a value

The output is as follows:
