I don't know what the intention was either, but around the time that C
was being developed, it was common to have both "scientific" and
"business" hardware modules. The "scientific hardware module" was
basically the floating point unit, while the "business hardware module"
was the BCD unit. So it's not surprising that there was a distinction
made between "real" and "float" by folks around the time when there were
several entirely different types of "real number" available.
