You didn't initialize this variable. Set it to 0.0 and it will
work.
Like how pointers are initialized to null automatically in D,
floats are auto initalized to NaN in D. The idea is to make use
of an uninitialized variable obvious quickly so you are
encouraged to initialize it.
Is there a reason the compiler doesn't identify this as an error?
prom+=nums[nem]; doesn't make sense if prom hasn't been
initialized. I'm not seeing how treating it as NaN is a solution.
Since it's possible that an NaN value is legitimate, you'd either
have to litter your code with assertions, or take a chance that
something that a problem will show up at a later date.
