*format and range of floating point numbers:*-
System-dependent; the
`double`

type of C. *results of*`REPRESENT`

when`float`is out of range:-
System dependent;
`REPRESENT`

is implemented using the C library function`ecvt()`

and inherits its behaviour in this respect. *rounding or truncation of floating-point numbers:*- System dependent; the rounding behaviour is inherited from the hosting C compiler. IEEE-FP-based (i.e., most) systems by default round to nearest, and break ties by rounding to even (i.e., such that the last bit of the mantissa is 0).
*size of floating-point stack:*-
`s" FLOATING-STACK" environment? drop .`

gives the total size of the floating-point stack (in floats). You can specify this on startup with the command-line option`-f`

(see section Invoking Gforth). *width of floating-point stack:*-
`1 floats`
