cell rounding of value automatically

Hello
i am working on this worksheet, and it is rounding off the value in certain cells automatically.
e.g. if i have a value 2.98 in cell c3 and i make the value of the cell in question say c56 =c3
it gives a value of 3

actually i discovered that the cell does not like any fractional number, if i directly try to input 3.1 it rounds it of to 3

Did you format the column as numeric and designate the precision?

actually it was a legacy sheet and some one had reduced the precison to zero decimal points :)
