7ec6bea991 [apps/proba] More seamless computation 
If the user computes P(x<a) which gives b, then presses OK on b, return
a.
This prevents some comutation errors such as for student distribution
with 0.05 degrees of freedom, P(x<9900000) then press ok on the result

88910e4e79 [poincare] PrintFloat: remove old assertion 
The assertion was true when we used a temporary buffer big enough to
hold longest floats to print inside (before copying its -maybe
truncated- content in the final buffer)

1cc09de9ae [apps/calculation] Invalid calculation height memoization when leaving 
the app.

Fix wrong memoization: in calculation app input '[[1+i, 2][3,4]]', change
the complex format to Polar, go back to the calculation app --> the
calculation height was no recomputed despite the fact that the approximation
output changed.

Émilie Feral
eb0f6153c5 [poincare] When reducing expressions, we check if an expression is a 
matrix to know if it can be permuted in a multiplication for example.
This check has to be 'recursive'/'deep' to detect cases like "cos(3×confidence(cos(2)/25,3))"
