wxMaxima is actually a user interface for maxima

How to prevent simplification/calculation of an equation in wxMaxima.

One might want to do this if one wants to see the input output in a nice
pretty looking form suitable for something like a LaTeX document or for
obtaining an image.

-use the command "simp:false" and then enter the expression on the new

line so that it will not be evaluated. To turn evaluation back on set
"simp:true:

--solution from here:

how-to.html

-note that a single quote mark like ' can prevent evaluation, but this

does not prevent "simplification" and numerical calculations are
considered simplification.

to force decimals enclose the command in "float".
-ex: float(3+2.5).

"Any time wxMaxima gives you a fraction when you want a decimal
equivalent, you can use the float command."

to control number of decimals displayed use "fpprintprec:4" (a different

number can be used instead of 4)

to force scientific notation use the "bfloat" command
-ex: bfloat(3e6*0.12)
