Syntax for non-decimal numbers |
SWI-Prolog implements both Edinburgh and ISO representations for
non-decimal numbers. According to Edinburgh syntax, such numbers are
written as <radix>’<number>
,
where <radix> is a number between 2 and 36. ISO defines
binary, octal and hexadecimal numbers using
0[bxo]<number>
. For example: A is 0b100 \/ 0xf00
is a valid expression. Such numbers are always unsigned.
