Web30 de jul. de 2024 · The floating point comparison is not similar to the integer comparison. To compare two floating point values, we have to consider the precision in to the comparison. For example, if two numbers are 3.1428 and 3.1415, then they are same up to the precision 0.01, but after that, like 0.001 they are not same. Web17 de abr. de 2024 · You should remember that the FPUs on these microcontrollers are often just single-precision FPUs. Single precision floating-point has only a 24 bit mantissa (with the hidden MSB) so you may get better precision from 32 bit integers in some cases.
