Gforth Manual
5.5.1 Single precision
By default, numbers in Forth are single-precision integers that are one
cell in size. They can be signed or unsigned, depending upon how you
treat them. For the rules used by the text interpreter for recognising
single-precision integers see 5.13.2 Number Conversion.
These words are all defined for signed operands, but some of them also
work for unsigned numbers: +, 1+, -, 1-,
*.
