Hello there,
how do i multiply a fraction and a whole number? Example 20% of 50,000.
I had gotten 0.2 using the following:
chk=echo 20 100 | awk `{print $1/$2}`
echo $chk
$chk \* 50000 displays the error: non-numeric expression. (1 Reply)
Suppose i have a file A
1*2*3*4
2*4*4*22
and second file B
2*3*4*5
4*4*6*7
By multiplying file A by file B that is file A by first column in file B respectively
output shud be
2*6*12*20
8*16*24*154
my code is
=$1
next
}
{for (f=1;f<=NF;f++) (2 Replies)
Hi,
I am writing a script in Bourne shell
#!/bin/sh
used=`quota -v | tail -1 | awk '{print $2}'`
total=`quota -v | tail -1 | awk '{print $3}'`
echo "$used"
echo "$total"
perc=`expr ${used} / ${total} * 100 | bc`
echo "$perc"
I want to get a percentage of quota used to total limit

Hi,
I would like to carry out a multiplication in a for loop but some how I get always zero. The result of the multiplication must be assigned to the variable x.
Here is teh code
for (( i=1;i<=15;i++)); do
x=$( printf "%s\n " 'scale = 10; i*5.0*335.0*3.0/1000.0' | bc)
echo $x $i... (5 Replies)
Hi all, newbie here.
Does anyone know if it is possible to use GCC or Clang to multiply
two unsigned numbers and have it use for intel instructions, the mull instruction or an imul. I can't figure how to word this to accomplish this task:
(int)(((unsigned long long)result * (unsigned)2290649225)... (4 Replies)
Dear All,
I am facing a problem and I would be Thankful if you can help
Hope this is the right place to ask this question

Hi,
I can't find out how to create correct code to get multiplication of each elements of array. Let's say I enter array into command line (2 3 4 5 6 8) and i need output 2*3*4*5*6*8=5760.
I tried this one, but answer is 0.

Hello all,
I have square matrices that look like the following, I want to merge these matrices together, and add the file names as headers. This is a simple example with two variables, actually I have ~1500 variables and 10 files.
The order of variables in the matrices are consistent.

I have two files. Row id in File1 matches the column id in file2 (starting from column7 )except the last 2 characters. File1 has 50 rows and File 2 has 56 columns. If the id matches I want to multiply the value in column3 of File1 to the entire column in File2. and in the final output print only... (11 Replies)
How can I produce this kind of output?
Enter a number: 3
MULTIPLICATION TABLE:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
When you enter a number, it should show you the corresponding multiplication table. Plus we need to use for loops that I do not actually know. Thanks in advance! Here is my... (2 Replies)

glmultmatrix
GLMULTMATRIX(3G) OpenGL Manual GLMULTMATRIX(3G)NAME
glMultMatrix - multiply the current matrix with the specified matrix
C SPECIFICATION
void glMultMatrixd(const GLdouble * m);
void glMultMatrixf(const GLfloat * m);
PARAMETERS
m
Points to 16 consecutive values that are used as the elements of a 4 x 4 column-major matrix.
DESCRIPTION
glMultMatrix multiplies the current matrix with the one specified using m, and replaces the current matrix with the product.
The current matrix is determined by the current matrix mode (see glMatrixMode()). It is either the projection matrix, modelview matrix, or
the texture matrix.
EXAMPLES
If the current matrix is C and the coordinates to be transformed are v = v 0 v 1 v 2 v 3, then the current transformation is C x v, or
c 0 c 4 c 8 c 12 c 1 c 5 c 9 c 13 c 2 c 6 c 10 c 14 c 3 c 7 c 11 c 15 x v 0 v 1 v 2 v 3
Calling glMultMatrix with an argument of m = m 0 m 1 ... m 15 replaces the current transformation with C x M x v, or
c 0 c 4 c 8 c 12 c 1 c 5 c 9 c 13 c 2 c 6 c 10 c 14 c 3 c 7 c 11 c 15 x m 0 m 4 m 8 m 12 m 1 m 5 m 9 m 13 m 2 m 6
m 10 m 14 m 3 m 7 m 11 m 15 x v 0 v 1 v 2 v 3
Where v is represented as a 4 x 1 matrix.
NOTES
While the elements of the matrix may be specified with single or double precision, the GL may store or operate on these values in
less-than-single precision.
In many computer languages, 4 x 4 arrays are represented in row-major order. The transformations just described represent these matrices in
column-major order. The order of the multiplication is important. For example, if the current transformation is a rotation, and
glMultMatrix is called with a translation matrix, the translation is done directly on the coordinates to be transformed, while the rotation
is done on the results of that translation.
ERRORS
GL_INVALID_OPERATION is generated if glMultMatrix is executed between the execution of glBegin() and the corresponding execution of
glEnd().
