Generate and return the result of applying the mathematical unary or binary operators \(\times/\) to the input argument(s).
Given two input arguments ref and val, the procedures of this generic interface return an array of size 2 whose elements are [ref / val, ref * val].
If ref is missing, then an appropriate default value is used.
- Parameters
-
| [in] | ref | : The input scalar of the same type and kind as the input val, representing the reference value in the operations.
(optional, default = 1.) |
| [in] | val | : The input scalar of
-
type
integer of kind any supported by the processor (e.g., IK, IK8, IK16, IK32, or IK64), or
-
type
complex of kind any supported by the processor (e.g., CK, CK32, CK64, or CK128), or
-
type
real of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128),
representing the value upon which the operators \(\times/\) will act. |
- Returns
binval : The output vector of size 2 of the same type and kind as val, containing the result of the \(\times/\) operations.

- Warning
- The condition
val /= 0 must hold for the corresponding input arguments.
This condition is verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.
-
The
pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.
