System-dependent; the double type of C.
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.
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).
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 Invoking Gforth).
