NAG Library Function Document
nag_max_sine_argument (X02AHC) returns the largest positive argument for which the
C compiler run-time library functions sin and cos
return a result with some meaningful accuracy.
nag_max_sine_argument (X02AHC) is a constant defined in the C Header file.
The trigonometric functions and supplied in some compiler run-time libraries do not return accurate results when their argument is large. Often the related accuracy of a result gets progressively worse as the argument gets larger. nag_max_sine_argument (X02AHC) gives a value beyond which the compiler run-time library returns results with no relative accuracy at all. Note that some run-time libraries do return accurate results for all arguments to and .
