In Origin 4.1, if a the abs value of a number inputted is larger/smaller than the maximum/minimum that can be internally represented as a floating point number, the worksheet showed -/0, respectively. This is quite OK and causes no unpredictable results. If you try inputting e.g. 1e150 with Origin 5.0 you wil notice that there is a bug (1e-106 is shown instad of the missing value -) caused probably by exponent overflow. This is particulary annoying when high precision data is imported to Origin: some very small values may be changed to extremely large ones.
