One of the nifty features of Gnumeric is that the size of a' cell expands to allow for up to 21 numerals. If the length of a number string exceeds 21 numerals, then the number' is displayed in scientific notation. This is a convenient format to handle and make sense of really long numbers! If the calculation draws up a figure that looks something similar to "1.243E+ 16", it simply means that the number is l.243x10"16. By default, Gnumeric spreads the width of the cell to support an accuracy of fifteen decimal spaces, which is sufficient even for rocket science. Manually dragging and reducing the width of the cell, reduces the number of decimal places displayed. Increasing the width of the cell, does not however, increase the number of decimal places displayed beyond the maximum of 15.
