( 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.
