Sorry, this should be, "FPREM can't _gain_ precision" with respect to
its operands.
Think of the binary representation with infinite precision, where the
exponent determines the position of the binary point, the binary
points are aligned between the two inputs, and the stored mantissa is
padded to the right with 0s. I don't see how FPREM could inject bits
to the right of the least significant LSB between the two inputs.
