    <p>I am using perl to produce an array of elements arranged as a single, tab-delimited line. However, only a portion of my array is like this. Other parts get printed as separate lines.</p> <p>Below is the relevant portion of the code.</p> <p>It is a foreach loop that has three conditional <code>for</code> loops embedded in it. The <code>push</code> command is used four times at four different <code>if</code>/<code>else</code> conditions. The particular array I'm having the issue with is called <code>@imputed_positions</code>. Several variables are defined near the beginning, which can be ignored. I don't think those are the problem.</p> <p>The output I get is correctly printed as a single line when the variable <code>$distance</code> is<code>&gt; 1</code>, even though those values get processed by 3 separate instances of the push command (the first three). Values for <code>$distance</code> that are <code>&gt; 1</code> and also floating point values for $distance get printed as a single line. When <code>$distance</code> is <code>&lt; 1</code> or <code>= 1</code>, they get printed as separate lines. These lines correspond to elements pushed into @imputed_positions by the last of the four push commands.</p> <p>I can't recognize an analogous problem within "Similar Questions," probably because I don't have a precise enough clue of what the issue is.</p> <p>Thanks!!!</p> <pre><code>foreach my $distance ( @distances ) { if ( $distance &gt; 1 &amp;&amp; ( int ( $distance ) != $distance ) ) { ###just asking whether $variable is an integer and whether it is &gt; than 1. my $rounded_up = rounding_up( $distance ); my $rounded_down = rounding_down( $distance ); my $up_distance = $distance/$rounded_up; my $down_distance = $distance/$rounded_down; my $abs_up = abs ( 1 - $up_distance ); my $abs_down = abs ( 1 - $down_distance ); if ( $abs_up &lt; $abs_down ) { for ( my $i = 0; $i &lt; $rounded_up; $i++ ) { push ( @imputed_positions, "IMP!$up_distance!A\tIMP!$up_distance!D\tIMP!$up_distance!I\t" ); } } else { for ( my $i = 0; $i &lt; $rounded_down; $i++ ){ push ( @imputed_positions, "IMP!$down_distance!A\tIMP!$down_distance!D\tIMP!$down_distance!I\t" ); } } } else { if ( $distance &gt; 1 ){ for ( my $i = 1; $i &lt;= $distance; $i++ ) { push ( @imputed_positions, "IMP!1!A\tIMP!1!D\tIMP!1!I\t" ); } } else { push ( @imputed_positions, "IMP!$distance!A\tIMP!$distance!D\tIMP!$distance!I\t" ); } } } #print @imputed_positions; #rounding down subroutine sub rounding_down { my ( $round_me ) = @_; my $rounded_down = int( $round_me ); return $rounded_down; } #rounding up subroutine sub rounding_up { my ( $round_me ) = @_; my $rounded_up = int( $round_me ) + 1; return $rounded_up; } </code></pre> <p>Maybe it would help if I explained the input. The @distances is just a txt file, where each line is a number. The numbers are all positive, and can be 0, integers, or floating point numbers. For eg, <code>@distance = ( 1, 3, 5.9999, 4.9, 3.1, 3.000001, 0, 0, 0.3 )</code>. </p> <p>When <code>@distance</code> contains the above elements, the output does not print as a single line, but rather looks like:</p> <pre><code>IMP!1 !A IMP!1 !D IMP!1 !I IMP!1!A IMP!1!D IMP!1!I IMP!1!A IMP!1!D IMP!1!I IMP!1!A IMP!1!D IMP!1!IIMP!0.999999998333333!A IMP!0.999999998333333!D IMP!0.999999998333333!I IMP!0.999999998333333!A IMP!0.999999998333333!D IMP!0.999999998333333!I IMP!0.999999998333333!A IMP!0.999999998333333!D IMP!0.999999998333333!I IMP!0.999999998333333!AIMP!0.999999998333333!D IMP!0.999999998333333!I IMP!0.999999998333333!A IMP!0.999999998333333!D IMP!0.999999998333333!I IMP!0.999999998333333!A IMP!0.999999998333333!D IMP!0.999999998333333!I IMP!0.98!A IMP!0.98!D IMP!0.98!I IMP!0.98!A IMP!0.98!D IMP!0.98!I IMP!0.98!A IMP!0.98!D IMP!0.98!I IMP!0.98!A IMP!0.98!D IMP!0.98!I IMP!0.98!A IMP!0.98!D IMP!0.98!I IMP!1.03333333333333!A IMP!1.03333333333333!D IMP!1.03333333333333!I IMP!1.03333333333333!A IMP!1.03333333333333!D IMP!1.03333333333333!I IMP!1.03333333333333!A IMP!1.03333333333333!D IMP!1.03333333333333!I IMP!1.00000003333333!A IMP!1.00000003333333!D IMP!1.00000003333333!I IMP!1.00000003333333!A IMP!1.00000003333333!D IMP!1.00000003333333!I IMP!1.00000003333333!A IMP!1.00000003333333!D IMP!1.00000003333333!I IMP!0 !A IMP!0 !D IMP!0 !I IMP!0 !A IMP!0 !D IMP!0 !I IMP!0.3 !A IMP!0.3 !D IMP!0.3 !I </code></pre>

    2. COHi, yes I can @WinnieNicklaus. Will try to format this reply correctly. Output expected: `IMP!1A IMP!1D IMP!1I IMP!0.01A IMP!0.01D IMP!0.001I ...` all as a single line for any value of $distance. What is see when I print is a separate line for each block of "IMP!$distance!A\tIMP!$distance!D\tIMP!$distance!I\t" whenever the $distance is 1 or < 1.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
