RE: WP 31S available at SourceForge
If you browse the STAT catalog when no statistical data is available, certain entries that invoke sigma_val() from stats.c set an error code in the background that will cause a bogus error message to appear after the next command or key press.
Here's how to reproduce the problem: 1. Clear registers: [f] [CLEAR] [R] [ENTER] [Y] 2. Browse the STAT catalog: [f] [STAT] [up] [EXIT] 3. Do almost anything, for example: [1] 4. Error message appears: "Too few data points" I've applied a simple fix in SVN: If sigmaN is zero, then sigma_val() bails out immediately without calling sigmaCheck() and setting an error code. This is very similar to what the 34S does. |
