Closes #1796.
This PR adds support in the parser for number literals in hexadecimal, octal and binary notation, suitably prefixed with the common
0x
,0b
and0o
. The documentation of the manual is updated accordingly.The stdlib function
std.string.to_number
wasn't updated to handle those new representations. I'm not sure yet if we should or if it should be a different function, accepting for example a baseb
. Or do both (maketo_number
the more generic but add more focused functions for specific bases or notations). In the meantime, I stuck to the most restrictive choice. We can reconsider later.
