    Never mind, found the cause, I used the wrong value to compare against, used _DST.mdig instead of _NUM->mdig

    Attempted to fix a rounding error but the fix seems to be ignored, I got other stuff to do now so hoping someone will spot the cause by the time I come back, here's the code & output:

    Figured out the fix:


    exp -= ((__DST.upto - final.bit) - __SRC.bits);

    Recheck the docs on scanf, your using the output wrong if memory serves me correctly

    Managed to fix the mantissa in division but still having problems with the exponent in that field, hoping someone here can see where I'm going wrong.

    Managed to fix it, this was all I needed to add after all: GitHub - awsdert/alu at 5f4c54b0303fa98c63a776212cd65a9241371707

    Appears the video was not as informative as it needed to be, ended up removing something that I thought was needed because of the video and got more correct results, still fails at a point and need...

    Forgot to use to separate bias's when I switched to assuming the temporary floats where double the size of the initial variables, fixed that and then analysed more of the flow and found that it's...

    Uncovered & fixed a bug with alup_mov_flt2flt, turned out the mantissa transfer was overriding 1 bit too many and corrupted the exponent as a result, still can't get the final exponent correct...

    Found a more informative video for FPN multiplication, made some changes to the function I'm using and I think I now how the mantissa correct (at least it looks correct from the raw binary), the...

    I thought it was C# given how the file extension is *.cs, I figured that was where that abomination of "double." came from

    Okay 1st you didn't fix the condition brackets so you still need to fix that, also:


    else (rdoMale.Checked == true && rdo30Over.Checked == true)

    How does that even compile? Did you mean this?...

    First I don't see how that compiles because from what I see you have an unclosed if condition at the start, also that condition is hard to read as is, start by using this format on it:

    Managed to fix it somehow, not quite sure how though so if someone feels like analysing the code here's the commit holding the code that passes the tests, the fix however leads me to believe I may...

    Well didn't expect much, not that it matters now but sorry I went silent for a while, combination of work and being to into gaming, reading and youtube lead me to leave this to the wayside for a...

    I think I was still misunderstanding something in the previous iteration, gotta shoot off to work so I'll just dump the code and output.

    OK I think I've nearly got it right on addition & subtraction, somehow missed the bias in the exponent though, anyone able to see where I lost the bias?

    Well I figured out why the other tests were passing, I had fed the same value into both sides of the operation, fixing that resulted in the expected failures, still haven't figure out where I'm going...

    As it happens my previous code where the negative was temporarily converted to positive prior to analysis and movement was actually correct, seems the bug I encountered that led me to believe...
