You haven't said what number you are trying to put into the cell, but I
suspect that the number is less than 0.5.
A quick test shows that if you set the cell to no decimal places then enter
a number less than 0.5 it is displayed 'rounded down' so it will show as
zero, if it's 0.5 or above it displays as 1.
If you need to put numbers less than 0.5 into youe cell you will have to
have at least 1 decimal place.

I put a number into a cell click on the next cell and the first cell reverts
to 0. If I format to number with 2 decimal places it will be ok but when I
try to take out decimal places it goes back to zero,
Help please
