I'm writing a PHP library that has a Number class that uses the bcmath extension for arbitrary precision. I have two questions: How much slower is bcmath compared to using the built-in int and float types? bcmath has an optional scale argument (that defaults to 3 digits). For an general purpose Number class that anyone could use, wha...

I've got a problem in Crystal Reports that's been bugging me for years, and I wondered if anybody might have a solution. I've got a few fields (data fields and formulae, numeric and string) all aligning to the left in design mode. When I move to preview mode, the numeric fields never line up with the other fields, and they are slightly...

I've tried unzipping a .numbers document and analysing the XML to see if I could interpret it but it's far too complicated. Also, I couldn't find the DTDs used by Apple. Judging by what's out there thi...

I have a codegear C++ builder project and added the JCL library to get a stackdump when an exception occurs. I get the stackdump, but the most important thing is missing, the line number where the exception actually happened. I get the function name, but if the function is 30 lines long it's not easy to guess where the problem is. Am I ...

Hey guys, Basically I've been trying to make a working hours calculator and I've run into a problem. When the start time's value is greater than the finish time (eg. start is 23 and finish is 19), the result comes up as a negative. So what I want it to do in that scenario is to then multiply the negative number by -1 to make it positi...
Hey guys, I basically have a working hours calculator in the works and I was wondering how I can disable certain numbers from being put into a field. For example, for the minutes field, I would like to prevent 61-99 being inputted. What sort of code would I need to make that work? ...
Right, basically I want to add two numbers together. It's for a working hours calculator and I've included parameters for a night shift scenario as an if statement. However, it now mucks up the day shift pattern. So I want to sort out that if the start time is below 12, then it'll revert to the original equation shown in the code instead...
We have to transform some XML that contain numbers in exponent (aka scientific) notation eg. <Value>12.34e12</Value> <Value>-12.34e-12</Value> rather irritatingly, we cannot use the sum() function and the like because the XSLT parser expects numbers to be in decimal format. [We are using the .Net XslCompiledTransform class...
First off, let me say that this is not homework (I am an A-Level student, this is nothing close to what we problem solve (this is way harder)), but more of a problem I'm trying to suss out to improve my programming logic. I thought of a scenario where there is an array of random integers, let's for example say 10 integers. The user will...
