Get OS-level system information
...get process CPU usage (without writing your own JNI code), but you need to cast the java.lang.management.OperatingSystemMXBean to a com.sun.management.OperatingSystemMXBean. This works on Windows and Linux, I haven't tested it elsewhere.
For example ... call the get getCpuUsage() method more freque...
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...

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...
