    The trouble with the floats

    Floating point variables are weird.

    • Their representation is not intuitve.
    • You need to take special care if you want to compare them.
    • Their exactness reduces with every step away from 0.
    • Most of the time we use them although, we actually do not need them.

    LED Debugging in Space

    There are to my knowledge, few languages and frameworks, that provide the documentation detail that Microsoft provides for the .Net Standard. and its languages. However, it is far more important in the hardware domain to have adequate documentation. An example for such a datasheet is Ambiq Micro’s Documentation for the Apollo MCU.
