 number of decimal places to show with an additional colon:</p>

<pre>Writeln(52.234567:1:3);</pre>

<p>The 'whole number' part of the real number is displayed as is, no matter whether it exceeds the first width (in this case 1) or not, but the decimal part is truncated to the number of decimal places specified in the second width. The previous example will result in 52.234 being written.</p>
