float or double to Integral
When converting a floating point type to an integer type, the value is rounded toward zero to
the nearest integer. Figure 18-12 illustrates the conversion conditions. If the rounded value is
not within the range of the target type, then
The CLR raises an
OverflowException
exception if the overflow checking context is
checked
.
C# does not define what its value should be if the context is
unchecked
.

decimal to Integral
When converting from

exception if the resulting value is not within the target type's range. Figure 18-13 illustrates the
conversion conditions.
