12.1.1.3.2 Byte Operations on Integers</H2> <P>

The byte-manipulation <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>functions</I></A> use <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>objects</I></A> called <A REL=DEFINITION HREF="26_glo_b.htm#byte_specifier"><I>byte specifiers</I></A> to designate the size and position of a specific <A REL=DEFINITION HREF="26_glo_b.htm#byte"><I>byte</I></A> within an <A REL=DEFINITION HREF="26_glo_i.htm#integer"><I>integer</I></A>. The representation of a <A REL=DEFINITION HREF="26_glo_b.htm#byte_specifier"><I>byte specifier</I></A> is <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A>; it might or might not be a <A REL=DEFINITION HREF="26_glo_n.htm#number"><I>number</I></A>. The <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>function</I></A> <A REL=DEFINITION HREF="f_by_by.htm#byte"><B>byte</B></A> will construct a <A REL=DEFINITION HREF="26_glo_b.htm#byte_specifier"><I>byte specifier</I></A>, which various other byte-manipulation <A REL=DEFINITION HREF="26_glo_f.htm#function"><I>functions</I></A> will accept. <P>
