VAL() should work for hex, & HEX$(), for negative
VAL() should work for hex, & HEX$(), for negative
I think VAL() should work for hexadecimal numbers and not only for decimal as it does now.
PRINT VAL("$FFFFFFF")
should print: 268435455.
I believe it would not be too difficult to implement since the code already exists for converting numbers in code.
PRINT $FFFFFFF
works now, and types: 268435455.
Especially now when HEX$() exists in the next prerelease (-39). HEX$() converts without $ as prefix, but I think that's OK since $ could be added easily if one wants. It's also similar to how it works in other BASICs, e.g. GW-BASIC: http://www.antonis.de/qbebooks/gwbasman/hexs.html
In GW-BASIC HEX$() also works for negative numbers, e.g. HEX$(-32768) is "8000", but negative numbers doesn't currently work with X16 BASIC HEX$().
I don't think it's necessary to implement VAL() for binary numbers, even though BIN$() exists, but if one did they should probably have % as prefix, e.g. %101.
FreePascal uses the same prefixes:
