How do I get whole and fractional parts from double in JSP/Java?
...
Converting double to int is almost always a bad idea. Because e.g. for (long)1.0e100 you will get 0. A lot of the times you need the double value simply "floored" for which there is floor(). If you want both integral and frac...

Here's a link explaining the math behind converting a decimal to a fraction:
http://www.webmath.com/dec2fract.html
And here's an example function for how to actually do it using VB (from www.freevbcode.com/ShowCode.asp?ID=582):
Public Function Dec2Frac(ByVal f As...
Passing variable number of arguments around

To pass the ellipses on, you have to convert them to a va_list and use that va_list in your second function. Specifically;
void format_string(char *fmt,va_list argptr, char *formatted_string);
void debug_print(int dbg_lvl, char *fmt, ...)
{

'Static readonly' vs. 'const'
... preferred (any short is an object, but not all object are short). So y is converted to short, and that overload is used. Then Equals compares two short of identical value, and that gives true.
When y is not a constant, no implicit conversion from int to short exists. That's because in general an i...

TargetType convertedRandomObject = (TargetType) randomObject;
If randomObject might be an instance of TargetType and TargetType is a reference type, then use code like this:

In C, a void * can be converted to a pointer to an object of a different type without an explicit cast:
void abc(void *a, int b)

int *test = a;

This doesn't help with writing your function in a more generic way, though.
