While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
* Continue MathTrig Breakup - Trig Functions
Continuing the process of breaking MathTrip.php up into smaller classes.
This round takes care of the trig and hyperbolic functions, plus a few others.
- COS, COSH, ACOS, ACOSH
- COT, COTH, ACOT, ACOTH
- CSC, CSCH
- SEC, SECH
- SIN, SINH, ASIN, ASINH
- TAN, TANH, ATAN, ATANH, ATAN2
- EVEN
- ODD
- SIGN
There are no bug fixes in this PR, except that boolean arguments are now
accepted for all these functions, as they are for Excel.
Taking a cue from what has been done in Engineering, the parameter validation
now happens in a routine which issues Exceptions for invalid values;
this simplifies the code in the functions themselves.
Consistent with earlier changes of this nature, the versions in the
MathTrig class remain, with a doc block indicating deprecation,
and a stub call to the new routines.
I think several more iterations will be needed to break up MathTrig completely.
