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.
A number representing ex, where e is Euler's number and x is the argument.
exp() is a static method of
Math, you always use it
Math.exp(), rather than as a method of a
Math object you
Math is not a constructor).
e to the power of a number very close to 0 will be very close to 1 and suffer from loss of precision. In this case, you may want to use
Math.expm1 instead, and obtain a much higher-precision fractional part of the answer.
Math.exp(-1); // 0.36787944117144233 Math.exp(0); // 1 Math.exp(1); // 2.718281828459045
