Suppose I have a series of index numbers that consists of a check digit. If I have a fair enough sample (Say 250 sample index numbers), do I have a way to extract the algorithm that has been used to generate the check digit? I think there should be a programmatic approach atleast to find a set of possible algorithms. UPDATE: The lengt...
I m looking for a faster implementation or good a approximation of functions provided by cmath. I need to speed up the following functions pow(x,y) exp(z*pow(x,y)) where z<0. x is from (-1.0,1.0) and y is from (0.0, 5.0) ...
Hi all! Maybe this sounds a little bit crazy, but I need to come up with a query to retrieve only letters out of an alphanumeric field. For example: TABLE 1234ADD 3901AC 1812OPA 82711AUU RESULTS EXPECTED ADD AC OPA AUU Thank you! ...
(I'm a beginner) My script uses the standard $c = 0; $t = count($array); while ($c < $t) { $blah = $array[$c]; ++$c; } rather extensively. But I just ran into a situation where I also need array_diff and it breaks that all to hell because now the numeric keys have gaps. I'm getting Undefined offset errors all over the place. H...

Hi, I'm very new to Ada and was trying to see if it offers double precision type. I see that we have float and Put( Integer'Image( Float'digits ) ); on my machine gives a value of 6, which is not enough for numerical computations. Does Ada has double and long double types as in C? Thanks a lot... ...
I have the strangest experience using taps to move data between my machine and Heroku. It works fine except that it seems to lose 0s directly behind the decimal place for my geo coordinates i.e. 50.0519322 for some reason gets set to 50.519322... no idea why. When I pull the data from the remote location ie. heroku db:pull... it works...

I would have dared say that the numeric values computed by Fortran and C++ would be way more similar. However, from what I am experiencing, it turns out that the calculated numbers start to diverge after too few decimal digits. I have come across this problem during the process of porting some legacy code from the former language to the ...
Hi everyone, Is_numeric() as well as is_int() returns false if the value is 0. What can i do instead to verify that a specific value is numbers only in PHP? Are we heading straight for the Regular Expressions camp, or are there some nice, handy feature for this out there already? Thanks! ...
