Data type conversion

+ +An operator must have +operands +of the same +type before it can carry out the operation. Because of this, C will perform +some automatic conversion of data types. +

+These are the general rules for binary operators (* + / % etc): +

If either operand is long double the other is converted to +long double. +
+
Otherwise, if either operand is double the other is converted +to double +
+
Otherwise, if either operand is float the other is converted +to float +
+
Otherwise, convert char and short to int +
+
Then, if an operand is long convert the other to long. +
