Math.exp()

The Math.exp() static method returns e raised to the power of a number. That is

𝙼𝚊𝚝𝚑.𝚎𝚡𝚙(𝚡)=exmathtt{operatorname{Math.exp}(x)} = mathrm{e}^x

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).

Beware that 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.

Syntax example: Math.exp(x)
