Strange Syntax

[czardas]

This project is slowly progressing at the current rate of opportunity (the rover). I have wrapped all the functions I plan to use in cascading error code (cascading because it forces the failure of subsequent functions), which will (theoretically) enable up to as many nested functions as the AutoIt interpreter can handle (I don't know what the limit is for nested functions, but I imagine it's big). Ignore the error return values for now (they are irrelevant anyway and liable to change). The first function is shown below:

Global $_KickBack_ = 0 ; Cascading error count for nested functions

; #FUNCTION# ====================================================================================================================
; Name...........: _Abs
; Description ...: Returns absolute value of expression.
; Syntax.........: _Abs($nExpression)
; Parameters ....: $nExpression - Any valid numeric expression.
; Return values .: Success   - Returns absolute value.
;                Failure   - Sets @error and returns 'NaN'.
; Author ........: ???
; Modified.......: czardas
; Remarks .......: Also works with 32-bit integers in hex string format as in the example
; Related .......:
; Link ..........:
; Example .......: MsgBox(0, "_Abs", _Abs("FFFFFFF6")) ; Returns 10 because 0xFFFFFFF6 = -10
; ===============================================================================================================================

Func _Abs($nExpression)
    If $_KickBack_ > 0 Then Return SetError(1, __HardError(), "NaN") ; Cascading error

    ; Force numeric params - strict implimentation for nested functions
    If Not IsNumber($nExpression) Then $nExpression = Dec($nExpression)
    If @error Then Return SetError(2, __HardError(), "NaN")

    Return Abs($nExpression)
EndFunc ;==>_Abs

Func __HardError()
    $_KickBack_ += 1
    Return $_KickBack_
EndFunc ;==>__HardError

The only problem I'm having is with the documentation: I don't know who to attribute the following native AutoIt functions to. I thought of setting AutoIt Dev Team or Jonathan Bennett as the authors (the only thing I'm adding are the error checks - more or less).

Who wrote the following functions?

Abs, ACos, ASin, ATan, BitAND, BitNOT, BitOR, BitRotate, BitShift, BitXOR, Ceiling, Cos, Dec, Exp, Floor, Hex, Log, Log10, Mod, Random, Round, Sin, Sqrt, Tan.

If not known, what name do you think I should put?

AutoIt Development Team would be fine but since they are all core functions; I would say that no attribution is necessary.

Thanks, I was thinking that I should leave the author field blank (unless the author is known).

The functions are not really designed to be used as a UDF, but rather to be used internally (In the language itself, the function names will not include underscore). I thought I'd stick with the standard UDF format for now in case someone wanted to make use of the final code.

Those are all standard mathematical functions. Attribution is stupid.

I just thought, perhaps I ought to put Achimedes.

Thanks for the responces.
