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:
result is max of 2^17 bits, and trying to retrieve high word >> 5 after a
mull or imul instruction. The above wording creates two multiply instructions.
This wording creates one instruction:
Not sure intel can handle first and that's why gcc breaks into two multiplies???
I believe the second will accomplish my task, but now need to recheck all my code.
Thanx, and I'll probably get kicked (was smoking and typing)

I'am doing a tutorial where a simple calculator was given, then i noticed that you can't actually multiply
this is how i have approached the problem so far. i just need if the user enters "*"
to change it to "/*" ,is it possible? i know that * means the name of the last file in the directory... (8 Replies)
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

Hi,
I am writing a script in Bourne shell

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,
i have file1 which looks like:
x1 y1 z1
x2 y2 z2
...(and so on)
and file2 which looks like:
a11 a12 a13
a21 a22 a23
a31 a32 a33
and i want to replace file1 with the following values:
x1' y1' z1'
x2' y2' z2'

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.
for i in $@; do
mult=$((mult*i))done
echo "mult: " $mult

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)
