My basic question was: why is i ∞ = 0 + i ∞ but it looks that (i ∞)^2 ≠ (0 + i ∞)^2 ? Reasoning for the second equation: (i ∞)^2 = -∞ while (0 + i ∞)^2 = 0 - ∞ + 2 i 0 ∞ (this expansion of the squared parenthesis doesn't assume anything IMO). For making both sides equal, 0 × ∞ must be zero. OTOH, W...

Even with an empty calculator (0 program steps) it won't allow to set more than 99 registers. In the same way, you can't create a matrix with more than 99 elements in a row or column. For instance, to create a 200-element matrix, you can't do 1 ENTER 200 DIM A, but you can do 10 ENTER 20 DIM A. I t...
What is the default memory allocation in V25? V16 is MEM: 30 99 0-0 If V25 is different, can you check again with this memory allocation. The affected registers are depending on it. It is also 30 99 0-0 but I was wrong. Corruption did occur with V25. Thanks for confirming. I was asking about the me...

I recently went back to some personal studies on the hp15c system, and pulled out my old 2012 "DM15CC" to test a few ideas. I updated it with the latest firmware (V16) available for this first generation machine (that was still in V8 up to now) and I was suprised to discover again an old bug related...
