# Exp# ( x# )

# Parameters

x = any number.

# Description

This is e^x where e = 2.71828... For the curious, e is defined by the infinite sum: 2 + 1/(2) + 1/(2*3) + 1/(2*3*4) + 1/(2*3*4*5) + ... See also Log()

# Example

; Exp example
; Exp(x) is the same as e^x.
; Actually, due to the approximate nature of floating point arithmetic
; these will not be exactly equal. But in the following example
; the difference is so small you can't see it.
e# = 2.71828182845905 ; over-specified, might help and can't hurt.
x# = .125 ; = 1/8
Print " x Exp(x) e^x "
Print "======= ========= ========="
For k = 1 To 7
Write " " + LSet( x , 7 )
Write RSet( Exp( x ), 10 )
Print RSet( e^x , 12 )
x = 2 * x
