I have been working through an error I am receiving with the above command. The error I get when I run it is:
TypeError: Error executing code in Maxima
CODE:
sage297 : integrate(sage293,sage294,sage295,sage296)$
Maxima ERROR:

Maxima encountered a Lisp error:
5883790627 is not of type FIXNUM.
Automatically continuing.
To enable the Lisp debugger set *debugger-hook* to nil.
However if I shorten the decimals to something like:
integral(integral(e^(-0.0026*(h - 11.1600000000000)^2 - 1.343724*(d - 2.85)^2)/pi, d, 0,Infinity), h, 0, Infinity).n()
Then the command runs fine without any issues. Now perhaps this is a bug, but really I do not need the level of precision that is in these commands. Of course I do not want numbers here but variables and it is evaluating the variables to this level of precision that is causing the issue. For example I say:
sage: f(d,h) = (1/(2*pi*0.61*13.85))*exp(-1/2*((d-2.85)^2/0.61^2+(h-13.85)^2/13.85^2))
sage: f
(h, d) |--> 0.05918210333195241758892111025625850742735*e^(-0.002606576392237615503916381029337017294634*(h - 11.16000000000000000000000000000000000000)^2 - 1.343724805159903251814028486965869389949*(d - 2.850000000000000000000000000000000000000)^2)/pi
Any ideas? P.S. I have searched around, but I have not found any that apply to just basic numbers in Sage.
