    bsl.h is a header file for information needed for the Board Support Library functions.

    The datasheet for the DAC explains the values that can be written to it. DACs have a fixed number of discrete values that can be converted from digital to analog. The digital value written to the DAC is technically a fixed-point value and not an integer.

    You may interpret your data in any way you wish, and convert that per your specifications to the appropriate fixed-point value to achieve the output voltage on the DAC.
