2e89f8b7de [poincare] Expression::simplifyForComplexFormat: Use a shortcut if the expression approximation is a real pure 2019-01-10 11:42:03 +01:00

7d9c49919c [poincare] simplifyForComplexFormat: before extracting 
ComplexCartesian/ComplexPolar, deepReduce instead of simplify to avoid
generating uselessly big trees. To make it work, implement shortcuts for
Power::complexCartesian and Power::complexPolar to return nice cartesian
expression when the power index is -1, 1/2 or -1/2

2f8ede54f2 [poincare] The sign function was used to decide wether an expression was 
of form -x. However, ln(0.3) has a negative sign but is not of form -x.
This commit fixes the misuse of ExpressionNode::Sign::negative.
For example, we do not turn sin(tan(9)) in -sin(-tan(9)) or
arcsin(sin(12)) in -arcsin(-sin(12) because tan(9)<0 and sin(12)<0

8c6ffa6d42 [apps] Fix graph X axis labels that read the same 
Scenario: just zoom in in a graph
Fix:
- Do not truncate labels.
- Label size is computed depending on available size and number of
 labels.
- If labels cannot be displayed properly, just display the minimal
and maximal labels!
