The following changes have been applied to src and lib folders:
regex replace: ([^"_])NULL ⇒ \1nullptr (8968 chgs in src, 1153 in lib)
Manually find/change: (void \*) nullptr ⇒ nullptr (1 case)
regex find: ".*?nullptr.*?"
Manually ~14 cases back to "NULL" in src, ~2 in lib
regex finds a few false positive where nullptr appears between two
strings in a function call
- use MathSpecial::square(x) instead of pow(x,2) for improved precision
and handling of small and negative numbers
- remove unused include statements
- no need to refetch the compute in every step. during init() is sufficient
