+If the source value can be exactly
+represented in the destination type, the result of the conversion is
+that exact representation[.](#2.sentence-1)

+If the source value is between two adjacent
+destination values, the result of the conversion is animplementation-defined choice of either of those values[.](#2.sentence-2)

+Otherwise, the behavior is undefined[.](#2.sentence-3)
