We have a table with a 'price' field of type NUMBER(20,7).. In TOAD I do this: update mytable set price = 1234567890123.1234567; Then I do this select: select price, to_char(price) from mytable PRICE TO_CHAR(PRICE) 1234567890123.12 "1234567890123.1234567" Question is, why does TOAD truncate the result when displayi...
Hi, Does anybody know (or may point to some source to read about) a method or algorithm to convert a number represented in binary numeral system into the ternary one (my particular case), or universal algorithm for such conversions? The solution I've already implemented is to convert a number to decimal first and then convert it into r...
I would like to parallelize my boost random number generator code in C++ with OpenMP. I'd like to do it in way that is both efficient and thread safe. Can someone give me pointers on how this is done? I am currently enclosing what I have below; this is clearly not thread safe since the static variable in the sampleNormal function is like...
Possible Duplicate: Is there an easy way in .NET to get st, nd, rd and th endings for numbers? Is there anything already built into C# that formats a number as a ranking position? By "ranking position" is mean one of ["st","nd,"rd","th"] eg : (1st, 2nd, 3rd, 4th). I know it'd be easy to write an extension for this, I'm just ...
Okay, this is quite an interesting challenge I have got myself into. My RegEx takes as input lines like the following: 147.63.23.156/159 94.182.23.55/56 134.56.33.11/12 I need it to output a regular expression that matches the range represented. Let me explain. For example, if the RegEx receives 147.63.23.156/159, then it needs to ...
I am trying to grab a number from a text box entry, convert it to string and grab the length of it. (IE: Perform a LEN(someInteger) on a number). I have been able to get it working, however there are some inconsistencies when the number is 0 or null. For example; -(IBAction)update { // inputField is the number pad textbox doubl...
Suppose I have variable "x" in bash. How can I test if it's some number? I tried if x=5; then echo "it is 5"; fi but that doesn't work, then I tried if x==5; then echo "it is 5"; fi but that also doesn't work, then I tried if [x==5]; then echo "it is 5"; fi but that also doesn't work, then I tried if [[x==5]]; then echo "it is 5"; fi...

Given an arbitrary python object, what's the best way to determine whether it is a number? Here is is defined as acts like a number in certain circumstances. For example, say you are writing a vector class. If given another vector, you want to find the dot product. If given a scalar, you want to scale the whole vector. Checking if some...
I'm sure this is a simple problem, but I'm comparing negative numbers in javascript i.e.: var num1 = -83.778; var num2 = -83.356; if(num1 < num2) { // Take action 1 } else { // Take action 2 } This script will always take action 2, even though num1 is less than num2. Whats going on here? ...
I was solving a puzzle, where im required to find the largest Prime Factor of a composite number entered by the user.

I'm appending my code below, I'd be grateful if anyone could help me out...
Hi, I'm trying to filter a number out of a string if that string starts with @. Here's what I thought would do the trick, but it returns nothing more than a blank page.
