Method Detail

add

public static LongValue add(long a,
                            long b)

Overflow safe addition of two longs

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a + b

overflowSafeAdd

public static NumberValue overflowSafeAdd(NumberValue a,
                                          NumberValue b)

Overflow safe addition of two number values.

Will not overflow but instead widen the type as necessary.

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a + b

overflowSafeAdd

public static NumberValue overflowSafeAdd(long a,
                                          long b)

Overflow safe addition of two longs

If the result doesn't fit in a long we widen type to use double instead.

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a + b

add

public static DoubleValue add(double a,
                              double b)

Addition of two doubles

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a + b

subtract

public static LongValue subtract(long a,
                                 long b)

Overflow safe subtraction of two longs

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a - b

overflowSafeSubtract

public static NumberValue overflowSafeSubtract(long a,
                                               long b)

Overflow safe subtraction of two longs

If the result doesn't fit in a long we widen type to use double instead.

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a - b

subtract

public static DoubleValue subtract(double a,
                                   double b)

Subtraction of two doubles

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a - b

multiply

                                 long b)

Overflow safe multiplication of two longs

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a * b

overflowSafeMultiply

                                               long b)

Overflow safe multiplication of two longs

If the result doesn't fit in a long we widen type to use double instead.

Parameters:

a - left-hand operand

b - right-hand operand

Returns:

a * b

multiply
