7. Integer conversion
· Implicit conversion, from small to big conversion
W Will not lose accuracy, not throwing an error
· Explicit conversion, from large to small conversion (forced conversion)
W may lose the accuracy and may throw an error
INT m = int.maxvalue; // Maximum value
Short S;
Checked {s = (short) m;} // Explicit conversion, will throw overflow errors
Long N;
Checked {s = m;} // implicit conversion, will not throw overflow errors
