Hello, I have a file, and one column has both positive and negative numbers. Does anyone know how I can calculate the total of all the values (i.e, +ve and -ve).

data 23 data
data 76 data
data -30 data
Thanks

Hi this is quite a simple question... I am new to LINUX/UNIX and so I am just trying to create a very basic program. The idea is that when the user runs the program (from the shell) they enter 3 values and the program will add them up:
"./sum 23 5 1
29"
my code for this program is as follows:

Hi
I figured how to add my list of numbers. However how do I count so that after a certain number it lists the line.
Example:
12 test1
46 test2
195 test3
174 test4
634 test5
185 test6
94 test7
So basically add the numbers and when the addition reaches 300 or less
print the... (8 Replies)
is there another way of doing the below:
echo "7 3 8 2 2 1 3 83.4 8.2 4 8 73 90.5" | bc
shell is bash. os is linux and sunos.
bc seems to have an issue with long range of numbers (12 Replies)

This works to add the numbers but can't figure an easy was to combine the 1st and 2nd column as the list is very long. awk '{s+=$3} END {print s}'

Hi again. Sorry for all the questions — I've tried to do all this myself but I'm just not good enough yet, and the help I've received so far from bartus11 has been absolutely invaluable. Hopefully this will be the last bit of file manipulation I need to do.
I have a file which is formatted as... (4 Replies)

math::roman(1.0) math::roman(1.0)
__________________________________________________________________________________________________________________________________________________NAME
math::roman - Tools for creating and manipulating roman numerals
SYNOPSIS
package require Tcl 8.3
package require math::roman ?1.0?
::math::roman::toroman i
::math::roman::tointeger r
::math::roman::sort list
::math::roman::expr args
_________________________________________________________________DESCRIPTION
::math::roman is a pure-Tcl library for converting between integers and roman numerals. It also provides utility functions for sorting and
performing arithmetic on roman numerals.
This code was originally harvested from the Tcler's wiki at http://wiki.tcl.tk/1823 and as such is free for any use for any purpose. Many
thanks to the ingeneous folk who devised these clever routines and generously contributed them to the Tcl community.
While written and tested under Tcl 8.3, I expect this library will work under all 8.x versions of Tcl.
COMMANDS
::math::roman::toroman i
Convert an integer to roman numerals. The result is always in upper case. The value zero is converted to an empty string.
::math::roman::tointeger r
Convert a roman numeral into an integer.
::math::roman::sort list
Sort a list of roman numerals from smallest to largest.
::math::roman::expr args
Evaluate an expression where the operands are all roman numerals.
Of these commands both toroman and tointeger are exported for easier use. The other two are not, as they could interfer or be confused with
existing Tcl commands.
