Intermediate results for single precision calculations

Hi,

I am working on a microcontroller that uses the ARM Cortex-R4F CPU. I would like to know that when performing single precision floating point calculations, where the FPU stores intermediate results in double precision before rounding and storing the final result in single precision?

Thanks, Mandeep

  • Hi, i do not need access to it but would like to understand whether single precision calculations on the FPU get better accuracy and precision because internally it uses double precision to store intermediate results before storing the final result in single precision format,
