How to set the number of decimals in a wave

Is there any way to set the number of decimals for all the points in a wave?
I'm not sure what you're asking, but I suspect that you are viewing the contents of a numeric wave in a table and are seeing the values up to only 6 decimal places, which is the default. If so, you can right click on the column in the table and choose Digits, then increase as you desire.
On a related note, is there a way to force a table to display, for example, 1.900 rather than just 1.9? This would be handy for checking to see if I mistyped data into a table - just seeing if all the decimal places line up ensures that I at least typed in the right number of digits.
Ok, thanks for your help. I made a table and changed the number of digits using the Digits menu (under the Table menu) and then selecting "Show Trailing Zeros" under the Format menu.
