integral competition HP50g vs. DM42

[Didier Lachieze]

Hi Thomas, I noticed a small difference between Free42 and the HP-42S: when trying to integrate a complex function on the HP 42S I get an "Invalid Type" error message, however on Free42 2.5.19 I don’t get any error message and the integrate function returns 0 instead which is a bit misleading.

Here is the function I’ve used for testing with LLIM=0, ULIM=5, ACC=0.01:

Code:

00 { 18-Byte Prgm }
01▸LBL "Fp"
02 MVAR "U"
03 0
04 RCL "U"
05 X↑2
06 COMPLEX
07 E↑X
08 END
