Recent versions of Logger Pro (3.5 and newer) allow a dynamic numeric range of 1.1e-99 to 1e99.

Older versions have more limited range.

If a column is set to display any number of decimal places, nonzero values may display as zero. To always display values, set the column to a specific number of significant figures (not blank or automatic). If you enter 1e-10, for example, LP or GA may display zero. If so, enable scientific notation or use significant figures instead of decimal place settings.

By using scale factors this numeric limitation will not prevent calculations.

Graphical Analysis 3.4 has relaxed rules on arithmetic precision (so that it is similar to GA for Win, an older version of GA) so that values between 10^99 and 10^-90 can be used.
