Math.exp()
The Math.exp()
function returns
e^x
, where x
is the argument, and e
is
Euler's number (also known as Napier's constant), the
base of the natural logarithms.
Syntax
Math.exp(x)
Parameters
x
-
A number.
Return value
A number representing e^x
, 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
