776 Appendix A: System Routines - Math push_degrees Declaration: void push_degrees (EStackIndex i, EStackIndex j, EStackIndex k) Category(ies): Math Description: Converts the input values, interpreted as degrees, minutes, and seconds, to the currently selected angle measure. Inputs: i - EStackIndex of internal tokenized degrees value. j - EStackIndex of internal tokenized minutes value. k - EStackIndex of internal tokenized seconds value. Outputs: Pushes the internal tokenized form of the result of converting the specified degrees, minutes, and seconds to the currently selected angle measure - radians or decimal degrees. Assumptions: Input values must be numbers, numeric symbols, or expressions that result in numbers or numeric symbols. Side Effects: May cause estack expansion, heap compression, or throw errors. Availability: On AMS 1.05 and higher. TI-89 / TI-92 Plus Differences: None See Also: push_radians Example: If the current angle setting is RADIANS, i indexes 30, j indexes 20, and k indexes 0, then push_degrees (i, j, k); pushes the value 91 † π/540 which is the equivalent number of radians onto the estack. If the current angle setting is DEGREES, i indexes 30, j indexes 20, and k indexes 0, then push_degrees (i, j, k); pushes the value 91/3 which is the equivalent number of degrees onto the estack.
