I covered that in my answer, which I was editing at the time to add more infomation. But the way you orginally worded it make is sound like the calcuations may not come out correctly, and you don't alway want to be percise because in a lot of calcuations needless percision can throw off you results. In programming which is what chips deal with you may not need to run instruction in FP32, and do it in FP16 instead which speeds up calcuations especially when the chips allow two FP16 instructions to run concurrently, if I remember correctly it is how many registers there are to run an instruction. Some chips use two 16-bit registers to run a 32-bit instruction and can change to doing two 16-bit instructions on the fly when there is optimization for it on the machine level. This allows for some secections of code to run faster. And on the other hand some registers are 32-bit registers only so even if you are putting 16-bit instructions through them they can only do one instruction at a time. |
Absolutely correct. Though that's already too technical I think. I went at it from a calculation and math perspective rather than from programming. And the smaller numbers might as well be imprecise, which wouldn't matter since higher precision isn't needed.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
