i have a list of numbers like this;
124
235
764
782
765
451
983
909
...
and i want to make a sum with the first 3 of them then the next 3 and so on.
124+235+764=1123
782+765+451=1998
...
some ideas? (4 Replies)
i know how to add two numbers using expr,
but if i have a file with hundreds of numbers, how do i add them all together, without typing them all one by one?
for example, file.txt contains
4
5
6
7
how can i give a command to add them, without typing
$ expr `4 + 5 + 6 + 7` (7 Replies)
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:

I am writing a bash script on ubuntu11.10
I have some string having numbers and letter and want to add all the numbers together
For example
1s2d23f
I want to perform
1 + 2 + 23 and store it in a variable (3 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)

Hello. Trying to add a column of numbers and combine the 1st and 2nd fields as uniq with the new total.
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)

DESCRIPTION
Each of these functions casts a ray (or rays) through a three-dimensional(3D) data set, then computes and returns the interpolated samples
at each step along the way.
In trilinear interpolation, the value at point P is computed from its eight surrounding neighbors based on the equation below.
P = (1-a)*(1-b)*(1-c)*P0 +
a*(1-b)*(1-c)*Px + (1-a)*b*(1-c)*Py + (1-a)*(1-b)*c*Pz +
a*b*(1-c)*Pxy + a*(1-b)*c*Pxz + (1-a)*b*c*Pyz +
a*b*c*Pxyz
where a, b, and c are the fractional parts of the coordinates of point P.
The trilinear interpolation is represented by the following figure:
Printed copy or docs.sun.com displays a figure that represents the trilinear interpolation.
In nearest neighbor operation, the sample value at point P is replaced by the value of the nearest neighbor voxel.
PARAMETERS
Each of the functions takes the following arguments:
rays Casting rays.
vol Volume data that consists of slices.
buffer Working buffer.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
