# EXPDAX Function (Math and Trig)

Returns e raised to the power of a given number.

## Syntax

EXP ( <Number> )
Parameter Attributes Description
Number

The exponent that is applied to the base e.

## Return values

Scalar A single decimal value.

Returns e raised to the power of a given number. The constant e is the base of the natural logarithm and is approximately 2.71828182845904.

## Remarks

EXP is the inverse of LN, which is the natural logarithm of the given number.

EXP(1) returns the approximate value of e.

To calculate powers of bases other than e, use the exponentiation operator (^) or the equivalent POWER function.
