`MERGE_BITS`

— Merge of bits under mask*Description*:`MERGE_BITS(I, J, MASK)`

merges the bits of`I`and`J`as determined by the mask. The i-th bit of the result is equal to the i-th bit of`I`if the i-th bit of`MASK`is 1; it is equal to the i-th bit of`J`otherwise.*Standard*:- Fortran 2008 and later
*Class*:- Elemental function
*Syntax*:`RESULT = MERGE_BITS(I, J, MASK)`

*Arguments*:-
`I`Shall be of type `INTEGER`

.`J`Shall be of type `INTEGER`

and of the same kind as`I`.`MASK`Shall be of type `INTEGER`

and of the same kind as`I`. *Return value*:- The result is of the same type and kind as
`I`.
