Usage Notes
This service accepts the following sub-classes of java.lang.Number: java.lang.Byte, java.lang.Double, java.lang.Float, java.lang.Integer, java.lang.Long, java.lang.Short.
This service applies the following rules for binary numeric promotion to the operands. The following rules are applied in order:
*If either operand is of type Double, the other is converted to Double.
*Otherwise, if either operand is of type Float, the other is converted to Float.
*Otherwise, if either operand is of type Long, the other is converted to Long.
*Otherwise, both operands are converted to type Integer.
These promotion rules mirror the Java rules for numeric promotion of numeric types.
