I'm trying to figure out if there is some function available that would take a
string as input and return a double value that is the complete evaluation of
the string?
So when asked for a numeric input, the user could just put in a number like
6.28 but also put in a formula like SQRT(2) or (3*(8+Q))/9.3 or Hypot(I,J)....
etc... using any random math operations in combination with math functions and
variables, without editing the code to create an expression to evaluate the
formula.

Any Ideas?
You could take a look at fpexprpars. See also here:
