Explicit Numeric Conversions C# with Example

Explicit casting operators can be used to perform conversions of numeric types, even though they don't extend or 
implement one another. 
double value = -1.1; 
int number = (int) value; 
Note that in cases where the destination type has less precision than the original type, precision will be lost. For 
example, -1.1 as a double value in the above example becomes -1 as an integer value. 
Also, numeric conversions rely on compile-time types, so they won't work if the numeric types have been "boxed" 
into objects. 
object value = -1.1; 
int number = (int) value; // throws InvalidCastException
