···1515* This loss of digits can be inevitable and benign (when the lost digits also insignificant for
1616 the final result) or catastrophic (when the loss is magnified and distorts the result strongly).
1717* The more calculations are done (especially when they form an iterative algorithm) the more important
1818- it is to consider this kind of problemm.
1818+ it is to consider this kind of problem.
1919* A method of calculation can be *stable* (meaning that it tends to reduce rounding errors)
2020 or *unstable* (meaning that rounding errors are magnified). Very often, there are both stable
2121 and unstable solutions for a problem.
