12.1.1.3.1 Logical Operations on Integers</H2> <P>
|
|
Logical operations require <A REL=DEFINITION HREF="26_glo_i.htm#integer"><I>integers</I></A> as arguments; an error of <A REL=DEFINITION HREF="26_glo_t.htm#type"><I>type</I></A> <A REL=DEFINITION HREF="e_tp_err.htm#type-error"><B>type-error</B></A> should be signaled if an argument is supplied that is not an <A REL=DEFINITION HREF="26_glo_i.htm#integer"><I>integer</I></A>. <A REL=DEFINITION HREF="26_glo_i.htm#integer"><I>Integer</I></A> arguments to logical operations are treated as if they were represented in two's-complement notation. <P>
|
|
The next figure shows <A REL=DEFINITION HREF="26_glo_d.htm#defined_name"><I>defined names</I></A> relating to logical operations on numbers. <P>
