No. They're saying that instead of floating-point, fixed-point math was used instead. Floating point hardware added a lot of cost to the chip back then and it was slow to perform in software, so everyone used integer math. The price of silicon has dropped so precipitously in the last 20 years that it's hard to imagine the lengths we had to go to in order to do very simple things.
