2020-09-03 07:23:29 +0100 | asked a question | How to handle very large numbers I want to play around with factorials. I found that Then I searched for a SageMath Stirling Formula, which I didn't find (only some related stuff), so I tried it myself: This gave me an error after some minutes: Then I tried s(10**9), there I got another error: So what can I do? Is there a special library for very large reals or int or some special commands for getting an approximation of how many decimals a factorial will have? Could I use the The reason why I'm asking is that I am rewriting a text which is 20 years old and there's a statement that And last but not least I would like to know if there is an upper bound for numbers that sage can handle. I thought not, but now I know otherwise ;-) Also hints to good literature on these topics would be appreciated. |

2020-04-05 14:07:20 +0100 | asked a question | How to find out the difference between M.determinant(), M.det() and det(M)? I am quite new to sagemath, but an experienced mathematician ... so I tried computing determinants for a given Matrix M and found different solutions. I found that M.det() is short for M.determinant() after searching the index and going further from there. But I did not find something for the syntax det(M). Inspire of being not a programmer, I am interested in a) where could I search to find the difference? b) what is the difference, if any? Many thank! Doris |
