( sf-addr -- ) ( F: -- r ) or ( sf-addr -- r )

Fetch the 32-bit IEEE single-precision number stored at sf-addr to the floating-point stack as r in the internal representation. If the IEEE single-precision significand has more precision than the internal representation, it will be rounded to the internal representation using the "round to nearest" rule. An ambiguous condition exists if the exponent of the IEEE single-precision representation is too large to be accommodated by the internal representation.
