EXP(x)

• where is the number .
• EXP() returns e raised to the power of a given number

## Description

• This function gives the   raised to the power of number.
• In  , where   represents the exponent of   or  .
• The approximate value of the constant   and it is equal to   or  .
• It is called the Mathematical Constant or Euler's Number or Napier's Constant.
• It is the base of natural logarithm.
• It can be calculate the sum of infinite series:
• And the inverse function of the natural logarithm function is the exponential function:

.

## ZOS

• The syntax is to calculate the EXP in ZOS is  .
• where   is the number .
• For e.g.,(-9)..5..2@EXP
Exponential
