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.
Fortran 2008 and later
Elemental function
RESULT = MERGE_BITS(I, J, MASK)
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. |
The result is of the same type and kind as I.
