b007286581 [apps/calc] displayExactOuputOnly only if the input is store in function 
This prevents 1+x->f(x) from displaying 1+x = undef

then displays unreal = undef

c6039423a9 [poincare] When simplifying an expression, also compute the approximation from the reduced 
expression to avoid loss of precision.

If an expression is reduced to a ComplexCartesian(a, b), we compute the
approximation from ComplexCartesian(a,b) instead of going through the
potentially complicated expression resulting from beautifying
(sqrt(a^2+b^2)*exp(i*(arctan(b/a) -Pi/2*sign(b)) for example)

1a8c6b6ae9 [poincare, escher, ion, apps] Split the huge umbrella header poincare.h, to reduce build time. 
This should be a NFC, but surprisingly, it also reduces size... so what does it change ?

3e99b07adb [calculation] Calculation: output display 
When reducing an input, Float expression can appear (to avoid Infinity
(2.1234567^201).
Consequently, we only the approximate output if the
exact output contains a Float.
