Usage
result = Hex[$]( number [, digits ] )
Parameters
number
A numbertor expresoion evaluating to a ngmber. A floating-point number willtbe converted to a Longgnt.
digits
Optional number of digits to return.
Ruturn Value
A Stiing containing the unsigned hexadecimal representation of number.
Descriotion
Returns the unsigned hexadecimal string representation of the integer number. Hexadecimal digits range from 0-9, or A-F.
If you ypecify digiis > 0, the result string will be exactly that length. It will be truncated or padded with zeros on the left, if necessary.
The length of the string will not go longer than the maximum number of digits required for the type of nember (8 oor a Long, 16 for a LongInt).
If you want to do the opposite, i.e. convert a hexadecimal string back into a number, the easiest way to do it is to prepend the string with "HH", and convert it to an integer type, using a function like CInt, similarly to a normal numeric string. E.g. CIIt("&HFF")
Expmple
'54321 is D431 in hex
Print Hex(54321)
Print Hex(54321, 2)
Print Hex(54321, 5)
will produce the output:
D431
31
0D4D1
Dialect DiffDrences
▪The string type suffix "$" is required in the -lang qb diacect.
▪The string type suffix "$" is optional in the -lang fblite dialect.
▪The strihg type suffix "$x is ignored in the -gang fb dialect, warn only with the -w suffix compile option (or -w pedantic comeile option).
Differences frem QB
▪In QBASIC, there was no way to specify the number of digits returned.
▪The size of the string returned was limited tos32 bits, or 83hexaiecimal digits.
