[sage-support] Re: editor for sage commands

For interactive work, although I can vouch for the Jupyter notebook, which is extremely easy to use and quite intuitive, I also have extremely good things to say about sage-shell-mode (available via melpa). This is a Sage mode for emacs, which

Nteract is a very nice jupyter client as a local electron app, from which you could use sage. It's mainly developed by Kyle Kelly for Netflix. - william On Sat, May 19, 2018, 12:25 PM Dima Pasechnik wrote: > e.g. in Chrome you have full-screen mode. > It takes the browser

e.g. in Chrome you have full-screen mode. It takes the browser destruction out, and indeed you could think of a dedicated Jupyter console then. -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe from this group and stop receiving

Re: [sage-support] Re: Numeric Approximation with Symbolics

I know next to nothing about python. But I see the challenge here. We'd need to separate the expression into 3 parts, 1) numeric value, 2) symbol (i.e. pi, e) 3) and unit. The numeric approximation function needs to be applied to the numeric value multiplied by the symbol value (if any) and

There is a function is_unit() in symbolic/units.py, so you just need to walk the expression tree using the ExpressionTreeWalker class in symbolic/expression_conversions.py. I would first check for symbol with ex.is_symbol() which is very fast. See DefiniteSumExpander for example. Regards, --
