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.
