22.3.2.1 Tilde R: Radix</H2> <P>
|
|
<TT>~</TT><I>n</I><TT>R</TT> prints <I>arg</I> in radix <I>n</I>. The modifier flags and any remaining parameters are used as for the <TT>~D</TT> directive. <TT>~D</TT> is the same as <TT>~10R</TT>. The full form is <TT>~</TT><I>radix</I><TT>,</TT><I>mincol</I><TT>,</TT><I>padchar</I><TT>,</TT><I>commachar</I><TT>,</TT><I>comma-interval</I><TT>R</TT>. <P>
|
|
If no prefix parameters are given to <TT>~R</TT>, then a different interpretation is given. The argument should be an <A REL=DEFINITION HREF="26_glo_i.htm#integer"><I>integer</I></A>. For example, if <I>arg</I> is 4: <P>
|
|
<P><DL><DT>* <TT>~R</TT> prints <I>arg</I> as a cardinal English number: <TT>four</TT>. <P><DD>
|
|
<DT>* <TT>~:R</TT> prints <I>arg</I> as an ordinal English number: <TT>fourth</TT>. <P><DD>
|
|
<DT>* <TT>~@R</TT> prints <I>arg</I> as a Roman numeral: <TT>IV</TT>. <P><DD>
|
|
<DT>* <TT>~:@R</TT> prints <I>arg</I> as an old Roman numeral: <TT>IIII</TT>. <P><DD></DL><P>
|
|
For example: <P>
|
|
<PRE>
|
|
(format nil "~,,' ,4:B" 13) => "1101"
|
|
(format nil "~,,' ,4:B" 17) => "1 0001"
|
|
(format nil "~19,0,' ,4:B" 3333) => "0000 1101 0000 0101"
|
|
(format nil "~3,,,' ,2:R" 17) => "1 22"
|
|
(format nil "~,,'|,2:D" #xFFFF) => "6|55|35"
|
|
</PRE>
|
|
</TT> <P>
|
|
If and only if the first parameter, <I>n</I>, is supplied, <TT>~R</TT> binds <A REL=DEFINITION HREF="v_pr_esc.htm#STprint-escapeST"><B>*print-escape*</B></A> to <A REL=DEFINITION HREF="26_glo_f.htm#false"><I>false</I></A>, <A REL=DEFINITION HREF="v_pr_bas.htm#STprint-radixST"><B>*print-radix*</B></A> to <A REL=DEFINITION HREF="26_glo_f.htm#false"><I>false</I></A>, <A REL=DEFINITION HREF="v_pr_bas.htm#STprint-baseST"><B>*print-base*</B></A> to <I>n</I>, and <A REL=DEFINITION HREF="v_pr_rda.htm#STprint-readablyST"><B>*print-readably*</B></A> to <A REL=DEFINITION HREF="26_glo_f.htm#false"><I>false</I></A>. <P>
|
|
If and only if no parameters are supplied, <TT>~R</TT> binds <A REL=DEFINITION HREF="v_pr_bas.htm#STprint-baseST"><B>*print-base*</B></A> to <TT>10</TT>. <P>
