Math.exp()

The Math.exp() function returns E raised to the power of a number.

Syntax​

Math.exp(x)

Parameters​

  • x
    • : A number.

Return value​

A nonnegative number representing ex, where e is the base of the natural logarithm.

Description​

Because exp() is a static method of Math, you always use it as Math.exp(), rather than as a method of a Math object you created (Math is not a constructor).

Beware that e to the power of a number very close to 0 will be very close to 1 and suffer from loss of precision. In this case, you may want to use Math.expm1 instead, and obtain a much higher-precision fractional part of the answer.
