DF@ d-f-fetch FLOATING EXT

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

Fetch the 64-bit IEEE double-precision number stored at df-addr to the floating-point stack as r in the internal representation. If the IEEE double-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 double-precision representation is too large to be accommodated by the internal representation.
