public class OpMultiply extends Operator
multiply
operator.
Conversions and promotions are handled as defined in
Section 5.6.2 of the
Java Language Specification, with the addiction of BigDecimal
/BigInteger
management:
If any of the operands is of a reference type, unboxing conversion (Section 5.1.8)
is performed. Then:
If either operand is of type BigDecimal
, the other is converted to BigDecimal
.
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.
If either operand is of type BigInteger
, the other is converted to BigInteger
.
Otherwise, if either operand is of type long, the other is converted to long.
Otherwise, both operands are converted to type int.

Implements the
multiply operator directly here for certain types
