VALUINT
Converts a string to an unsigned 32bit integer
Syntax:
declare function Valuint ( byref strnum as const string ) as ulong
declare function Valuint ( byref strnum as const wstring ) as ulong
declare function Valuint ( byref strnum as const wstring ) as ulong
Usage:
result = Valuint ( strnum )
Parameters:
strnum
the string to convert
Return Value:
Returns a Ulong value of the converted string
If the first character of the string is invalid, Valuint will return 0.
If the first character of the string is invalid, Valuint will return 0.
Description:
For example, Valuint("10") will return 10, and Valuint("10.60") will return 10 as well. The function parses the string from the left, skipping any white space, and returns the longest number it can read, stopping at the first non-suitable character it finds. Any non-numeric characters, including decimal points and exponent specifiers, are considered non-suitable, for example, Valuint("23.1E+6") will just return 23.
Valuint can be used to convert integer numbers in binary / octal / hexadecimal format, if they have the relevant identifier ("&B" / "&O" / "&H") prefixed, for example: Valuint("&HFF") returns 255.
If you want to convert a number into string format, use the Str function.

Examples:
Dim a As String, b As ulong
a = "20xa211"
b = ValUInt(a)
Print a, b
a = "20xa211"
b = ValUInt(a)
Print a, b
20xa211 20
