Exp Function

Calculate the numeric value of a natural logarithm.

Namespace: XSharp.RT
Assembly: XSharp.RT (in XSharp.RT.dll) Version: 2.19

Syntax

Copy

 FUNCTION Exp(
	nExponent AS USUAL
) AS FLOAT

public static Float Exp(
	Usual nExponent
)

Request Example View Source

Parameters

nExponent: Type: Usual
The power to which e is to be raised.

Return Value

Type: Float
A floating point number that is equivalent to the value e raised to nExponent.

Remarks

Exp() calculates the value y (the antilogarithm) of the following equation:

Copy

1e^x = y

where e is the base of natural logarithms (2.71828...) and x is nExponent. Exp() and Log() are inverse functions.

Examples

This example demonstrates several invocations of Exp():

Copy

1? Exp(1)                    // 2.72
2SetDecimal(10)
3? Exp(1)                        // 2.7182818285
4? Log(Exp(1))                // 1.0000000000
