sf-addr -- ) ( F:
r -- ) or
(
r sf-addr -- )
Store the floating-point number
r as a 32-bit IEEE
single-precision number at
sf-addr. If the significand
of the internal representation of
r has more precision
than the IEEE single-precision format, it will be rounded using
the "round to nearest" rule. An ambiguous condition exists if
the exponent of
r is too large to be accommodated by the
IEEE single-precision format.
