The double type of C, which is IEEE DP FP (binary64) on most
platforms (exception: ARM with soft floats).
REPRESENT when float is out of range: ¶Represent produces results for all inputs. For infinities, it
produces as much of “infinity” or “-infinity” as fits in the
buffer. For NaNs, it produces as much of “NaN” as fits in the
buffer. The remaining buffer is filled with spaces. For infinities
and NaNs, flag2 (valid) is false, otherwise true.
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).
1 floats.
