2011-09-27 02:21:03 +0200 | commented answer | numeric approximation?? Wow thanks. Worked like a charm. I was thinking that may be my problem, but didn't know how to access that. Thanks again. |

2011-09-27 02:20:40 +0200 | marked best answer | numeric approximation?? My guess is that you're trying to call .n() or float not on the number but on the _equation_. For example: You really want to get at the expression on the right: or maybe |

2011-09-26 21:53:39 +0200 | asked a question | numeric approximation?? So I have an equation that solved (symbolically) looks something like this: r == 1/488486532917088881338043645348028612608*sqrt(1271541785242875384103984923680382406444427305742938801212457) - 80406364132947/169706962694363951398912 and when I do anything to evaluate this numerically I get a TypeError? Right now I am copying and pasting this output into wolfram alpha, but really there has to be a better way? Furthermore if I try to evaluate the equation with find_root(...) I get this error: File "expression.pyx", line 984, in sage.symbolic.expression.Expression.__float__ (sage/symbolic/expression.cpp:5596) TypeError: unable to simplify to float approximation ?! |
