12.6.1.1470 F>D f-to-d FLOATING
( -- d ) ( F: r -- ) or
( r -- d )
d is the double-cell signed-integer equivalent of the integer portion of r. The fractional portion of r is discarded. An ambiguous condition exists if the integer portion of r cannot be represented as a double-cell signed integer.
Note:
Rounding the floating-point value prior to calling F>D
is advised, because F>D rounds towards zero.
