Function Exp() Foundation

Calculates the value of e to the power of x

Syntax
Exp( <nExponent> ) --> nAntilogarithm
Parameters
<nExponent>
<nExponent> is a numeric value to which e is raised.
Return

Exp() raises the numeric value e (base for natural logarithms, 2.71828...) to the power specified by the exponent <nExponent>.

Description

The mathematical function Exp() calculates the antilogarithm of <nExponent>. The number y, whose natural logarithm is x, is designated as the antilogarithm of x. It is calculated by the following exponential equation:

y = e**x

The number e is the base of the natural logarithm (2.71828...) and x is <nExponent>. The value for <nExponent> may not exceed 46, or a numeric overflow is generated.

When the result is displayed, the number of decimal places is only dependent on SET DECIMALS and not on the current SET FIXED setting.

PROCEDURE Main 

   ? Exp(1)       // result: 2.72 
   ? Exp(46)      // result: 94961194206024490000.00 

   SET DECIMALS TO 15 

   ? Exp(1)       // result: 2.718281828459045 
   ? Exp(46)      // result: 94961194206024490000.000000000000000 

   ? Log(Exp(1))  // result: 1.000000000000000 
   ? Exp(46.1)    // result: ********************.***************
