The Math.expm1()
function returns e^x - 1
, where x
is the argument, and e the base of the natural logarithms.
Math.expm1(x)
x
A number.
A number representing e^x - 1
, where e
is Euler's number and x
is the argument.
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).
Math.expm1(-1); // -0.6321205588285577 Math.expm1(0); // 0 Math.expm1(1); // 1.718281828459045
