#3760 new Bug

Number() bug with oversized integer values

Reported by: jchd18 Owned by:
Milestone: Component: AutoIt
Version: 3.3.14.5 Severity: None
Keywords: Cc:

Description

Number($s) erroneously converts values outside [MinInt64, MaxInt64] to MinInt64 or MaxInt64.

MinInt64 = -9223372036854775808
MaxInt64 = 9223372036854775807

Example:

Number("22222222222222222222222222222222")  ; returns 9223372036854775807

Workaround version returning a FP values in such case:

Func _Number($s)
	Local $a = StringRegExp($s, "^([-+]?)0*(\d+)$", 1)
	If Not @error Then
		Local $l = StringLen($a[1])
		; in case the int is oversized
		If $l > 19 Or ($a[0] <> "-" And $a[1] > "9223372036854775807") Or ($a[0] = "-" And $a[1] > "9223372036854775808") Then Return Number($s & ".0")
	EndIf
	Return Number($s)
EndFunc
