## numaverage

Find the average of a set of numbers.

• -i Only return the integer portion of the final sum.
• -I Only return the decimal portion of the final sum
• -m Find the mode (most occuring) of the list of numbers, or when there's more than one mode, the first completed mode.
• -M Find the median (middle number) of the list of numbers.
• -l When finding the median and the count of numbers in the set is even, use the lower middle number instead of the upper middle number.
$echo -e '1\n2\n3\n5.0\n\n' | numaverage -i 2$ echo -e '1\n2\n3\n5.0\n\n' | numaverage -I
.75
$echo -e '1\n2\n3\n5.0\n\n' | numaverage -M 3$ echo -e '1\n2\n3\n5.0\n\n' | numaverage -l
2.75

## numbound

Find boundary numbers in files or STDIN.

• -l – Return the lower bound number in the set (the minimum number)
$echo -e '1\n2\n3\n5.0\n\n' | numbound 5.0$ echo -e '1\n2\n3\n5.0\n\n' | numbound -l
1

## numgrep

This program is the numeric equivilent of the grep utility.

## numinterval

Show the numeric intervals between each line in a file.

$echo -e '1\n2\n3\n5.0\n\n' | numinterval 1 1 2 ## numnormalize Normalize a set of numbers. By default between 0 and 1. $ echo -e '1\n2\n3\n5.0\n\n' | numnormalize

## numprocess

This program mutates numbers as it encounters them.

Convert from celcius to fahreheit degrees. Multiply by 9, divide by 5 and add 32:

7

\$ numrange /1..10,15..20/
1 2 3 4 5 6 7 8 9 10 15 16 17 18 19 20

## numround

A program that rounds off numbers it encounters.

• -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>.

## numsum

• -i Only return the integer portion of the final sum.
• -I Only return the decimal portion of the final sum.
• -c Print out the sum of each column.
• -r Print out the sum of each row.
• -x <n> Specify a comma seperated list of columns to print.
• -y <n> Specify a comma seperated list of rows to print.
• -s <string> Specify a string to use as a seperator for columns. This defaults to be consecutive whitespace (\s+).
