Median() function and the unknown real number

Reported by: Pedro Gea Owned by: Víctor de Buen Remiro
Priority: highest Milestone:
Component: Various Version: head
Severity: critical Keywords:
Cc: Pedro Gea

Description

Median with unknown real numbers depends on the order of the numbers.

See that:
Real Median(?,3,2);
Real Median(2,?,3);
Real Median(3,2,?);

There are three different values for the permutations of these numbers.

This bug probably affects other median functions
like: SetMedian(), MedianS(), ...
