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.
