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.
