I should state that I am a Mathematica beginner but I checked the questions about machine vs arbitrary precision (such as: this one ) and I continue to have the following issue while trying to evaluate an expression:
After various calculations which include square roots and integrals, I arrive at a function
foo[x_] which I want it to return a number.
On the contrary, it returns a numerical expression as shown below, together with the return values of different tests I made.
My end goal is to use
foo to calculate other expressions, as well as to
Plot this it, which I cannot do at the moment.
Any suggestions? Thanks in advance!
