- 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 .
. Can be changed at startup
with the command-line option -f
.
- width of floating-point stack:
-
1 floats
.
