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 there.
I've used Sed to pull out some numbers, can it also be used to perform calculations on these numbers?
For example I have a text file with a list of weights however some of them are presented like 24x18g, I actually need it to multiple the two number and display it as 432g

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)
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)
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)

scope
scope(n) [incr Tcl] scope(n)
NAME
scope - capture the namespace context for a variable
SYNOPSIS
scope name
DESCRIPTION
Creates a scoped value for the specified name, which must be a variable name. If the name is an instance variable, then the scope command
returns a string of the following form: @itcl object varName This is recognized in any context as an instance variable belonging to object.
So with itcl3.0 and beyond, it is possible to use instance variables in conjunction with widgets. For example, if you have an object with
a private variable x, and you can use x in conjunction with the -textvariable option of an entry widget. Before itcl3.0, only common vari-
ables could be used in this manner.
If the name is not an instance variable, then it must be a common variable or a global variable. In that case, the scope command returns
the fully qualified name of the variable, e.g., ::foo::bar::x.
If the name is not recognized as a variable, the scope command returns an error.
Ordinary variable names refer to variables in the global namespace. A scoped value captures a variable name together with its namespace
context in a way that allows it to be referenced properly later. It is needed, for example, to wrap up variable names when a Tk widget is
used within a namespace: namespace foo {
private variable mode 1
radiobutton .rb1 -text "Mode #1" -variable [scope mode] -value 1
pack .rb1
radiobutton .rb2 -text "Mode #2" -variable [scope mode] -value 2
pack .rb2 } Radiobuttons .rb1 and .rb2 interact via the variable "mode" contained in the namespace "foo". The scope command guarantees
this by returning the fully qualified variable name ::foo::mode.
You should never use the @itcl syntax directly. For example, it is a bad idea to write code like this: set {@itcl ::fred x} 3 puts "value
= ${@itcl ::fred x}" Instead, you should always use the scope command to generate the variable name dynamically. Then, you can pass that
name to a widget or to any other bit of code in your program.
