sentences:  All floating-point operations are largely implemented in microcode across the processor family and are thus fairly slow.On the V60/V70, the 32-bit floating-point operations take 120/116/137 cycles for addition/multiplication/division, while the corresponding 64-bit floating-point operations take 178/270/590 cycles.The V80 has some limited hardware assist for phases of floating-point operations—e.g.
