How to go from decimal to numerical values?
snappy title to grab attention. maybe not stupid, but bleeding difficult to use, talk about a non-obvious, non-intuitive interface; I want to enter a hex value, and have the calculator convert that to decimal. So, I use the pull-down, choose 'hexadecimal', enter the hex value, then change the pull down to 'decimal', expecting to see the decimal (base 10) value. What do I see? The display just adds the hexadecimal base to the end of the hex value I just wrote! Where's my decimal (base 10) number damn it? I can't for the life of me work it out.
View 4 Replies View Relatedi have a small script that takes the time in seconds(this is a very long number like 615.232145457577) and i convert it to minutes or hours by dividing by 60 or 3600 respectively. I would like to be able to get the result with maybe upto to 2 decimal values.
If i do echo "613.568787987975 / 3600" |bc -l
this gives: .17043577444110416666
How can i just get .17
what i am trying to do is to allow the user to key in data such as "23.23" or "24" , as it is the price of certain objectsHow am i able to design a check which will allow me to prevent users from typing in input such as "ab.21" or "rfrr" as this field is purely a numerical field. The problem i am facing is i tried using this search code.
Code:
echo "read this"

I am using the code:
sort -k1
but it prints it by sorting the second column.
Using PHP 5.x. I would like to sort a set of values first numerically, then alphabetically. For example, here's my code so far:

I have fiddled with array_multisort but I can't seem to get my head around it or the many sort routines in PHP.
I have this .txt file

3574216 W
5264994 M
2656889 A
I want to sort it by the numerical order of column. After sort, I wish to get output like
2656889 A
3183630 R
3574216 W
5264994 M
anyone knows how to use sort to do that? or any other command?
I am using some "Numerical Recipes in C" routines in my C code.(I am using ludcmp() & lubksb().)These are used to find inverse of a matrix.After compiling my c code, I get following warning messages.I have not understood them at all.

I just received a spreadsheet. Column B contains thousands of rows that look like this:
Giant Red Pencil 0.99
Case 2.99
Green Box 1.49
Ruler 0.59
Spiral Ring 0.10
So each cell contains the item and price. I need the corresponding cells in column C to contain only the price like this:
0.99
2.99
1.49
0.59
0.10
How do I extract just the price from column B and put it in column C ?
I just noticed there doesn't seem to be a decimal point button on the calculator (gcalctool 5.32.0) when it is in programming mode. I'm using Fedora 14 (32-bit).

I want to count the digits in between the text in a file.
e.g.

I have a script in the works that reads an MP3 file and gets the track length. Trouble is, it gives me the total seconds, like this:

View 3 Replies View RelatedI'm writing an if statement where a variable is a number such as 14.05 (this is actually a temperature) and I want to compare it to a predefined value, sample code below:
Code:
I have all sorts of errors regardless of how I do this (double quotes, square brackets). The best idea I've had is stripping off the decimal place so it's a 4 digit number (e.g warning=1503 and DEV_TMP=1405) however this seems a little unnescessary and I'm sure there's an easier way of achieving the same thing.

How would I rename all files with a leading decimal point recursivley? I some how got all my music files to have a decimal point.I tried the below and got a " sed argument to long".[CODE]find /media/MUSIC -type f -name "*.wma" | xargs -0 sed -i 's/.(.*)/1/'[CODE]
Another question, can i just use -type f with out -name ? I am sure that all the files got the decimal point added as the first character.

I am looking for comprehensive documentation of the SMART values that are reported in Palimpsest.For example, I am getting the following result:
Attribute: Reallocated Sector Count
Assessment: Warning

Value: 1 sector
I would like to find a very thorough description of the meaning of these values, how they relate to each other, and how to interpret them.
I had installed ubuntu 10.10 long back but never really used it much due to academical commitments. I had installed ubuntu on a separate partition of 20 gb. I don't remember exactly what all values I had selected for various partition and I was very much confused while installation! I somehow managed to install it and this is what I got while booting my laptop! Apart from that my home and desktop size were very less.
I remembered myself giving 6 gb to swap (as I considered swap to be important). Here is what I get when I mount type in terminal!! I have downloaded the new ubuntu 11.04 and I want to start over again by totally formatting my 20 gb hard disk that I created!! Also I want to keep at least 30 gb for my new drive! What sizes exactly should I used for this installation for various file systems!
I've implemented a few custom system calls in my Ubuntu kernel, but I'm having some issues with the return values. Each function returns a variety of non-negative integers depending on which error is encountered. However, when I'm testing the system calls, the only negative value that gets returned to the user program is -1, regardless of what I have in the code.
Is there some special path I have to take to get the proper return values?
X programs specify parameter "-display dpy". I have failed with many guesses at dpy values. I find no definition in man pages and elsewhere. I know it is simple. I request examples.

View 6 Replies View RelatedI have a script that runs lots and lots of root commands, copying files in /usr/...stuff like that, then i want to switch users back to the original user and run some gconf tweaks, I need to update a series of gconf values for a user after copying all the root files, but I noticed once your in root, any gconf values you change, change roots information, not the user who started the script useing sudo.
So i was wondering how you would run a script as root, then after your done with all the root commands, "un-root" to the current user who started the script and run the gconf edits:
I put together this so far. It a script that you run, it detects if it was started as root and if not it asks for root password and re-spawns its self exiting out the first instance, then the script runs, switches to the original user after all files are copyed over and starts to run the Military Time custom format update.
