8.195 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 or a boz-literal-constant.
J	Shall be of type INTEGER with the same kind type parameter as I or a boz-literal-constant. I and J shall not both be boz-literal-constants.
MASK	Shall be of type INTEGER or a boz-literal-constant and of the same kind as I.

Return value:

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