RM G 2 4 19 Accuracy Requirements (GNAT Reference Manual)

### 6.63 RM G.2.4(19): Accuracy Requirements ¶

> “The versions of the forward trigonometric functions without a `Cycle` parameter should not be implemented by calling the corresponding version with a `Cycle` parameter of `2.0*Numerics.Pi`, since this will not provide the required accuracy in some portions of the domain. For the same reason, the version of `Log` without a `Base` parameter should not be implemented by calling the corresponding version with a `Base` parameter of `Numerics.e`.”

Followed.
