numbers

Example. 123456, and we want the third from the right ('4') out. The idea in practise is to access each digit seperately (ie. 6 5 4 3 2 1). C/C++/C# preferred. A more efficient implementation might be something like this: char nthdigit(int x, int n) { while (n--) { x /= 10; } return (x % 10) + '0'; } This saves the effort of converting all digits to string format if you only want one of them. And, you don't have to allocate space for the converted string. If speed is a concern, you could precalculate an array of powers of 10 and use n to index into this array: char nthdigit(int x, int n) {

I want to check if a variable has a number in it, I just want to see if there is one I don't care if it has any thing else in it like so: "abc" - false "!./#()" - false "!./#()abc" - false "123" - true "abc123" - true "!./#()123" - true "abc !./#() 123" -true There are easy ways of doing this if you want to know that is all numbers but not if it just has one. Thanks for your help. You can use the strcspn function: if (strcspn($_REQUEST['q'], '0123456789') != strlen($_REQUEST['q'])) echo "true"; else echo "false"; strcspn returns the length of the part that does not contain any integers. We

Just asked by my 5 year old kid: what is the biggest number in the computer? We are not talking about max number for a specific data types, but the biggest number that a computer can represent. Infinity is not allowed. UPDATE my kid always wants to print as well, so lets say the computer needs to print this number and the kid to know that its a big number. Of course, in practice we won't print because theres not enough trees. This question is actually a very interesting one which mathematicians have devoted a fair bit of thought to. You can read about it in this article , which is a

Can anyone explain to me why this code doesn't works correctly: var num = '10'; Number(num); console.log(typeof(num));//string parseInt(num); console.log(typeof(num));//string parseFloat(num, 10); console.log(typeof(num));//string console.log('-------------'); var num = '10'; var string = 'aklñjg'; num = Number(num); string = Number(string); console.log(typeof(num));//number console.log(typeof(string));//number num = parseInt(num); string = parseInt(string); console.log(typeof(num));//number console.log(typeof(string));//number console.log('++++++++++++++++'); var num = '10'; var string =

I am trying to keep track of the the scores of the lowest numbers and if I find the lowest scores of those players I don't want them to play again in the next round. I have gotten to the point of storing those low player value into the array but I only want them to be stored ONCE. for(int i =0; i < player.length; i++){ for(int j =1; j < player.length; j++){ if(player[j] < player[i]){ min[i] =j; System.out.println(min[i]+" "+round+" "+playerList.get(j)); } } } Do 2 separate loops instead. One to find lowest number, second to collect indexes. int minValue = 1000000; // for(int i =0; i< player

How does one specify the maximum value representable for an unsigned integer type? I would like to know how to initialize min in the loop below that iteratively computes min and max lengths from some structs. var minLen uint = ??? var maxLen uint = 0 for _, thing := range sliceOfThings { if minLen > thing.n { minLen = thing.n } if maxLen < thing.n { maxLen = thing.n } } if minLen > maxLen { // If there are no values, clamp min at 0 so that min <= max. minLen = 0 } so that the first time through the comparison, minLen >= n . nmichaels https://groups.google.com/group/golang-nuts/msg
