8.195 MERGE_BITS — Merge of bits under mask

Synopsis:

RESULT = MERGE_BITS(I, J, 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.

Class:

Elemental function

Arguments:
IShall be of type INTEGER, UNSIGNED or a boz-literal-constant. I and J shall not both be boz-literal-constants.
JThe type shall be the same type as I with the same kind type parameter or a boz-literal-constant.
MASKShall be of the same type as I, J or a boz-literal-constant.
Return value:

The result is of the same type and kind as I.

Standard:

Fortran 2008 and later, extension for UNSIGNED (see Unsigned integers)
