WebMay 6, 2024 · It was at the point where I was trying to use 2 PICs, one basically as a floating-point processor, and the whole project got kludgy. Not to mention all the fun I had learning how to do floating point division in assembly on a processor that only does 8-bit integer add and subtract. Because of the speed, it just works on the Ardunio. Some floating-point hardware only supports the simplest operations: addition, subtraction, and multiplication. But even the most complex floating-point hardware has a finite number of operations it can support – for example, no FPUs directly support arbitrary-precision arithmetic. When a CPU is executing a program that calls for a floating-point operation that is not directly supported by the hardware, the CPU uses a series of simpler floating-point operations. In syste…
