Converts a string to a 32bit integer

	//result// = **Valint** ( //strnum// )
##
{{fbdoc item="param"}}
	##//strnum//##
		the string to convert

{{fbdoc item="ret"}}
	Returns a ##[[KeyPgLong|Long]]## value of the converted string

	If the first character of the string is invalid, ##**Valint**## will return ##0##.

{{fbdoc item="desc"}}
	For example, ##**Valint**("10")## will return ##10##, and ##**Valint**("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, ##**Valint**("23.1E+6")## will just return ##23##.
	
	##**Valint**## can be used to convert integer numbers in [[KeyPgBin|binary]] / [[KeyPgOct|octal]] / [[KeyPgHex|hexadecimal]] format, if they have the relevant identifier (##"&B"## / ##"&O"## / ##"&H"##) prefixed, for example: ##**Valint**("&HFF")## returns ##255##.
	
	If you want to convert a number into string format, use the ##[[KeyPgStr|Str]]## function.
