numround

NUMROUND(1)						User Contributed Perl Documentation					       NUMROUND(1)

NAME

       numround - A program that rounds off numbers it encounters.

SYNOPSIS

       numround [-cdfhV] <FILE>

       | numround [-cdfhV]   (Input on STDIN from pipeline.)

       numround [-cdfhV]     (Input on STDIN.  Use Ctrl-D to stop.)

DESCRIPTION

       numround will simply round decimal numbers to the nearest integer or to a factor of any number using the -n option.  You can also force it
       to round up (ceiling) or round down(floor) using the -c and -f options.

OPTIONS

	   -c	   Force the number to be rounded up. Ceiling.
	   -f	   Force the number to be rounded down. Floor.
	   -n <n>  Round numbers to the nearest factor of <n>.

	   -h	   Print out some helpful information about numround.
	   -V	   Increase verbosity.	This will print out numbers as it finds them.
	   -d	   Debug mode.	For developers only.

BUGS

       numround currently only rounds the first number on each line.  Eventually this will be changed as all the numeric utilities are developed.

       numround will drop off the decimal places in decimal numbers.  This may cause some calculations to be in error, depending on how you are
       using the data.

SEE ALSO

       numaverage(1), numbound(1), numinterval(1), numnormalize(1), numgrep(1), numprocess(1), numsum(1), numrandom(1), numrange(1)
