### HEX

Returns the hexadecimal of the given number

Syntax:
Usage:
result = Hex[\$]( number [, digits ] )

Parameters:
number
A number or expression evaluating to a number. A floating-point number will be converted to a longint.
digits
Optional number of digits to return.

Return Value:
A string containing the unsigned hexadecimal representation of number.

Description:
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 long, 16 for a 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 Cint, similarly to a normal numeric string. E.g. Cint("&HFF")

Examples:
'54321 is D431 in hex
Print Hex(54321)
Print Hex(54321, 2)
Print Hex(54321, 5)
will produce the output:

```D431
31
0D431```

Dialect Differences:
• The string type suffix "\$" is obligatory in the -lang qb dialect.
• The string type suffix "\$" is optional in the -lang fblite dialect.
• The string type suffix "\$" is forbidden in the -lang fb dialect.

Differences from QB:
• 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.
