rounding up (or down) issue

Greetings,

I have data lines in  a file like these whose
components add up to 100:

1.73   0.45   98.72
1.88   23.11  75.01
16.88  0.88   82.24



Yet, when attempting to round down (or up)
resulting data will not be 100 in total:

e.g. 2nd row , rounded up:
2   24   75    = 101

e.g. 2nd row , rounded down:
1   23   75    = 99


I need to round them up (or down) for re****ting
purpose in which the line show up like:

2%     24%    75%   = 101%



How does one get round this?
i.e. Any way to get 100 after rounding up (or down)?


Thanks,
Farid
