To say one version of modulus is bug prone and the other is not, is itself
erroneous.
I have just found another bug in my code caused by it,

C99 leaves it as implementation defined. D defines it in the specification.
Those are fundamentally different.

I didn't realize that C99 did specify it. Thanks for the correction.

The point is, the programmer has to take extra care regardless.
All definitions of modulus are a land mine, as they are all arbitrary. There
is no such

I am not the only one making mistakes with the C-style modulus, I know of other

Is there any use for the way C-style modulus interacts with
negative numbers? It seems little more than broken on the basis
of making positive number modulus operations efficient back when
C was created.

Even Fortran is now and then adding important features today. Generally only
dead languages stop changing. Please keep this in mind.
