Truncate Two decimal places without rounding
...our function will cause overflows. You should use Int64 if you really must cast it to an Integer. The question would be why you would want to incur that extra overhead anyway since Truncate returns Decimal integrals anyway. Just do something like: decimal step = (decimal)Math.Pow(10, precision); re...

C library function to perform sort
..._function, which takes in two
arguments of type "const void", which can be cast to appropriate data structure, and then
return one of these three values:
negative, if a should be before b
0, if a equal to b
positive, if a should be after b
1. Comparing a list of integers:
simply cast a and b to...
Use C++ with Cocoa Instead of Objective-C?
I would like to write applications that use C++ and the Cocoa frameworks because Apple is not making Carbon 64-bit capable. C++ seems to be pretty vanilla in its implementation on Linux and Windows but on Mac OS X it seems like additional Apple specific pieces of code are required (like an Obj-C wra...

How do I split a multi-line string into multiple lines?
...
@lpapp, I totally agree. splitlines() is semantically (and functionally, since it uses universal newlines and omits a trailing empty line) better than split('\n'). Back then (2008) I was just a newbie Pythonista and grepping though my scripts now shows that I too am using splitli...
Round a double to 2 decimal places [duplicate]
...et 200.34.
if you wanted to always round down we could always truncate by casting to an int:
double val = ....;
val = val*100;
val = (double)((int) val);
val = val /100;
This technique will work for most cases because for very large doubles (positive or negative) it may overflow. but if you know...
