The solutions of equations that need numerical approximations to be
solved are now computed base on the undeveloped equation (instead of
fully the expended one used to identify polynomials)
This allow (x-10)^7=0 to yield x=10 as result (9.95 before)

Fix bug: when entering "e^234" as a parameter of a model keeping floats,
the FloatParameterController would accept the number (because e^234 is
defined in double) and store an undefined value in the model (because
e^234 is undefined in float).
