Fedora :: No Decimal Point In Programming Calculator?
Dec 9, 2010I 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).

Ubuntu :: New Calculator - Change The Pull Down To 'decimal' Expecting To See The Decimal (base 10) Value
Mar 31, 2011snappy 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.

Software :: Rename Hidden Files / Rename All Files With A Leading Decimal Point Recursivley?
Jul 25, 2011How 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.
Programming :: Convert Hex To Decimal Inside Script With Awk

Is there any way to do that with awk, preferably in a oneliner? Would printf be an option?
Programming :: Bash: Convert Decimal To Minutes:seconds?
Jan 13, 2011I 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:

Aug 11, 2010I'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.

General :: How To Get Decimal Value
Jul 4, 2011i 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

View 4 Replies View RelatedProgramming :: Operator For Floating Point Comparison?
May 10, 2011I know it is wrong to use the "==" operator to compare the equality of two floating point numbers. Logically it would seem that if the "==" operator is not usable for floating point comparison, then the "<=" operator would also not be usable. Is this true? The lack of google search results on this topic made me think that it must be true. If that is true, then is it true that the only way to compare floats with <= or >= is with something like the code below? Code: bool smaller_than_or_equal(float a, float b) {
if ( fabs(a-b) < EPSILON){return true;}
else if (a < b) {return true;}
else {return false;}
} I think this is a general question, but if specifics are necessary, I am using the C++ language to code at the moment.
Programming :: IEEE Floating Point Format?
Jun 5, 2011I'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.

View 1 Replies View RelatedNetworking :: Policy Routing Using Two Point-to-point Links?
Aug 27, 2009This one has been driving me nuts for some days now:My Gentoo box which is acting as an internet gateway has two point-to-point interfaces, ppp0 (PPPoE to my ISP) and ppp1 (PPTP VPN link to IPREDator). Packets from my local network are just routed through ppp0 and now the fun part starts: I want to MARK (netfilter...) all packets originating from one specific user on that box in order to use another routing table that will contain a default route via the ppp1 interface.Marking seems to work fine as does the second routing table. But quite mysteriously (at least for me), the packets sent out on ppp1 contain the wrong source IP address, namely the address associated with ppp0.So here is what ifconfig and friends tell me:Network interfaces:

Ubuntu Networking :: Point To Point (ad-hoc) SSH Over USB Or Ethernet?
Jun 3, 2010I was wondering if there is any way to SSH from one computer to another and completely bypass a router or any other network infrastructure. The reason I ask is because my robot ( same one in this post ) often needs to change which wireless network it automatically connects to, however it is getting annoying to have to drag out a monitor and plug it in along with a keyboard and mouse every time this needs to happen. Instead I'd much rather just plug my laptop into the other computer, SSH in and change the network myself.
So I thought I would ask you kind people if this is possible. The robot's computer has unused ethernet and USB ports, and I'd like to use those if at all possible (and with linux, anything is possible! -- sorta). I thought about doing something with ad-hoc, but this would limit my range (in infrastructure mode I can control the thing anywhere there is internet), and is to be avoided.
