Syntax
Math.exp(x)
Parameters
x
- A number.
Return value
A number representing ex
, where e
is
Euler's number and x
is the
argument.
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).
Examples
Using Math.exp()
Math.exp(-1); // 0.36787944117144233
Math.exp(0); // 1
Math.exp(1); // 2.718281828459045
