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)xBecause 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).
