Math.expm1()
The Math.expm1() function returns
e^x - 1, where x is the argument, and
e the base of the natural logarithms.
Syntax
Math.expm1(x)
Parameters
x-
A number.
Return value
A number representing e^x - 1, where e is
Euler's number and x is the argument.
Description
Because expm1() is a static method of Math, you always use it
as Math.expm1(), rather than as a method of a Math object you
created (Math is not a constructor).
Examples
Using Math.expm1()
Math.expm1(-1); // -0.6321205588285577
Math.expm1(0); // 0
Math.expm1(1); // 1.718281828459045
