MVBITS
— Move bits from one integer to anotherMoves LEN bits from positions FROMPOS through
FROMPOS+LEN-1
of FROM to positions TOPOS through
TOPOS+LEN-1
of TO. The portion of argument TO not
affected by the movement of bits is unchanged. The values of
FROMPOS+LEN-1
and TOPOS+LEN-1
must be less than
BIT_SIZE(FROM)
.
Fortran 90 and later, has overloads that are GNU extensions
