For example sometimes I read English texts in which the author says for example that at the beginning the ambient temperature was 68°F, then after a drop of 12°F he observed [A], after another drop of 9°F he observed [B], and so on. All these conversions in °C are boring to do… With newRPL there is only one conversion to do: 70_°F gives 20_°C Then it's straightforward: 12_Δ°F - gives 13.33_°C 9_Δ°F - gives 8.33_°C, and so on. I like that feature a lot! (10-03-2015 06:15 PM)Claudio L. Wrote: I consider a bad thing if the result of a command depends on flags. I believe (as much as possible) that output of a command should depend exclusively in the input provided, not on system-wide flags. I don't know yet if this is a good idea. Existing programs for the HP50g with trigonometric functions inside will have to be entirely edited to be used with newRPL. Also, I'm afraid that function names like SIN COS TAN are so natural that it will be very easy to make errors in writing or editing programs… However, if you implement this feature, I think I would prefer command names like SIND, SING, instead of DSIN, GSIN… Jean-Charles |
