Admissible values

[compsystems]

Hello, where can I find information about the admissible values in hp-prime as the following table?


Thanks

Hello,

We do not really have such a table. Probably because they are so many functions!

However, here is some information that might help you (and probably is in the doc somewhere)
In HOME calculations.
Numbers are in the -9.99999999999e499 to 9.99999999999e499 range
Internally, most calculations are done with numbers in the -9.99999999999999e49999 to 9.99999999999999e49999 range.
Some of the internal calculations are only done in the -9.99999999999e499 to 9.99999999999e499 range (matrices comes to mind)

So, any calculations that leads to numbers that are outside this range will cause over/underflow

As much as possible, calculations that lead to large internal values during calculations, but not for the final result, try to minimize such internal numbers by using log based calculations.


In the CAS, if you are working with floating point numbers, the range is in the +/-1e308 range (double).
When working with integer, the limit is the memory (and computation time).
