What are the number formats for SigmaDSP?

In the SigmaStudio help file, some of the algorithms have input and outputs specified as integer or decimal. Also, in the SigmaDSP datasheets, there are references to 28.0 and 5.23. Also, in SigmaStudio, sometimes cells will have other formats like 5.19. What does this mean?

  • From the datasheet:

    The parameter RAM is 32 bits wide and occupies Address 0 to Address 1023. Each parameter is padded with four 0s before the MSB to extend the 28-bit word to a full 4-byte width.

    If writing these values from a microcontroller, do we have to ensure that these padding bits are always 0, or is their value ignored?
