This is plain wrong. Integers are not converted to floating-point numbers.
They simply used the same multiplier hardware.

While in the first Pentium 4 processors the complex integer unit and the
floating-point unit did indeed share the multiplier hardware, this is no
longer the case in current processors of the Pentium 4 generation. Sharing
the multiplier unit causes serious contention problems, and it definitely
cannot have been the preferred solution, only one Intel had to use until it
could afford an even larger die.
