Math.exp()

The Math.exp() function returns ex, where x is the argument, and e is Euler's number (also known as Napier's constant), the base of the natural logarithms.

Math.exp(x)

x

A number.

A number representing ex, where e is Euler's number and x is the argument.

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).

Math.exp(-1); // 0.36787944117144233
Math.exp(0);  // 1
Math.exp(1);  // 2.718281828459045
