Rounding off decimals to the nearest number in PERL
Hi Guys,

I am generating a statistical report , below is the snippet of the code :
Quote:
$sliceStartTime = &convertTime($sTime);
$sliceEndTime = &convertTime($eTime);
$totalTime = $sliceEndTime - $sliceStartTime;
$nSlices = $totalTime / ($slice * 60);

Now, $nSlices stands for the time duration,meaning,the statistics will be displayed for that particular time duration. Trouble is, for certain values of $totalTime (which is the end time - start time ), i end up getting decimal values for $nSlices. I am coding this in PERL, and i wish i could find a way to round off the decimals to the nearest whole number. For example, if the value of $nSlices is 23.323232 i would like to round it off to 23, and if the value of $nSlices is 23.7878787 i would like to round it off to 24. Basically,anything over .5 and above gets rounded off to the next whole number, and anything below .5 gets rounded off to the previous number. Anyways that i can achieve this? Help would be much appreciated!

sylseg-sk-training

sylseg-sk-training(1)						   USER COMMANDS					     sylseg-sk-training(1)

NAME

       sylseg-sk-training - train the statistic for the syllabic segmentation

SYNOPSIS

       sylseg-sk-training [--color] [--dl debug level] [--help] [<input file>]

DESCRIPTION

       The sylabic segmentation is esential for some linguistic or speech recognition applications. Depending on the language either rule based or
       statistical approach is beying used. For Slovak the statistical approach seems to be more suitable.

       sylseg-sk-training creates the necessary data for one of the statistical approaches for	the  syllabic  segmentaion.  The  input  data  are
       expected  to  be word segmented into syllables. The syllabic separator should be "-".  If no input file is specified, the standard input is
       expected.  The output is written in to the file. The filename is input filename with the extension  ".statistics".  If  standard  input	is
       used, then the output filename is syl_output.statistics.

       The design of the sylseg-sk-training is language independent. Theoretically it should work for any language.

OPTIONS

       --color
	      Enable color output.

       --dl   Set  the	debug  level. Control the amount of displayed information The debug level 0 displays nothing. The maximum level 5 displays
	      full debugging report. The default debug level is 1.

       --help display a short help text

EXAMPLES

       Use file aaa.txt as training input and set up debug level to 3:
	      sylseg-sk-training --dl 3 aaa.txt

EXIT STATUS

       sylseg-sk-training returns a zero if the training  succeeds
