Blank String Cast To Int Is A Number?

Recommended Posts


Local $number = ""
If isNumber(Int($number)) And  Then MsgBox(0,"","Blank is a number!")

The above snippet evaluates to true.  I'm not sure if this is a bug.

The below snippet is the workaround to avoid the problem of an empty string provided evaluating to a number.

Local $number = ""
If IsNumber(Int($number)) And StringLen(StringStripWS($number, $STR_STRIPALL)) Then MsgBox(0, "", "Blank is a number!")

Once again Autoit's lack of typing claims a victim! :D

The blank string is automatically converted to a number by Int - and becomes numeric 0 as there is no numeric content at the start (see Number in the Help file). Using string/numeric functions on the opposing datatype nearly always ends in tears - best to force the conversion yourself beforehand. ;)

Technically the Int() function is converting the string to a 0...which is a number.

edit: Melba's got this. :)
