	//result// = **Hex**[$]( //number// [, //digits// ] )
##
{{fbdoc item="param"}}
	##//number//##
		A number or expression evaluating to a number.  A floating-point number will be converted to a ##[[KeyPgLongint longint]]##.
	##//digits//##
		Optional number of digits to return.

{{fbdoc item="ret"}}
	A [[KeyPgString string]] containing the unsigned hexadecimal representation of ##//number//##.

{{fbdoc item="desc"}}
	Returns the unsigned hexadecimal string representation of the integer ##//number//##. Hexadecimal digits range from 0-9, or A-F.

	If you specify ##//digits//## > 0, the result string will be exactly that length.  It will be truncated or padded with zeros on the left, if necessary.

	The length of the string will not go longer than the maximum number of digits required for the type of ##//number//## (8 for a ##[[KeyPgLong long]]##, 16 for a ##[[KeyPgLongint longint]])##.

	If you want to do the opposite, i.e. convert a hexadecimal string back into a number, the easiest way to do it is to prepend the string with ##"&H"##, and convert it to an integer type, using a function like ##[[KeyPgCint Cint]]##, similarly to a normal numeric string.  E.g. ##[[KeyPgCint Cint]]("&HFF")##

'54321 is D431 in hex

{{fbdoc item="lang"}}
	- The string type suffix ##"$"## is obligatory in the //[[CompilerOptlang -lang qb]]// dialect.
	- The string type suffix ##"$"## is optional in the //[[CompilerOptlang -lang fblite]]// and //[[CompilerOptlang -lang fb]]// dialects.

{{fbdoc item="diff"}}
	- In QBASIC, there was no way to specify the number of digits returned.
	- The size of the string returned was limited to 32 bits, or 8 hexadecimal digits.
