Math.exp() function returns e raised to the power of a number. That is
A nonnegative number representing ex, where e is the base of the natural logarithm.
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).
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(-Infinity); // 0 Math.exp(-1); // 0.36787944117144233 Math.exp(0); // 1 Math.exp(1); // 2.718281828459045 Math.exp(Infinity); // Infinity
