Handle mpc80 generation where zero padding of 9.999 was writing 010.00

[petervanwylen]

I found a unique situation where if day was 9.9999996 or higher, rasec was 9.9996 or higher or decsec was 9.996 or higher, the current would would write out something like 010.00 or 010.000 because the if statement was padding it and then the fixed setprecision was rounding up to 10. Using setfill and setw with setprecision fixes this problem. I hope this helps!
