## Fn.ExpN

Returns the exponential of a given value with a given accuracy.

### Syntax

Fn.ExpN(Val:RAT,Acc:INT):RAT

### Description

This function returns the exponential of `Val` rounded to the

given accuracy `Acc`.

@param

*Val*The value of which to compute the exponential.@param

*Acc*The desired accuracy.@return The exponential of

`Val`rounded to the given accuracy`Acc`.

#### Example

R := Fn.ExpN(2, 30); Dec(R, 40); 7.389056098930650227230427460575 -------------------------------
