Method Details

absImpl

public Number absImpl(Number number)

Description copied from class: NumberMath

Computes the absolute value of a number.

Subclasses must implement this method according to type promotion hierarchy rules.

Specified by:

absImpl in class NumberMath

Parameters:

number - the operand

Returns:

the absolute value

addImpl

public Number addImpl(Number left,
 Number right)

Description copied from class: NumberMath

Adds two numbers.

Subclasses must implement this method according to type promotion hierarchy rules.

Specified by:

addImpl in class NumberMath

Parameters:

left - the left operand

right - the right operand

Returns:

the sum

subtractImpl

public Number subtractImpl(Number left,
 Number right)

Description copied from class: NumberMath

Subtracts two numbers.

Subclasses must implement this method according to type promotion hierarchy rules.

Specified by:

subtractImpl in class NumberMath

Parameters:

left - the minuend

right - the subtrahend

Returns:

the difference

multiplyImpl

public Number multiplyImpl(Number left,
 Number right)

Description copied from class: NumberMath

Multiplies two numbers.

Subclasses must implement this method according to type promotion hierarchy rules.

Specified by:

multiplyImpl in class NumberMath

Parameters:

left - the first multiplicand

right - the second multiplicand

Returns:

the product

divideImpl

public Number divideImpl(Number left,
 Number right)

Description copied from class: NumberMath

Divides two numbers.

Subclasses must implement this method according to type promotion hierarchy rules.

Specified by:

divideImpl in class NumberMath

Parameters:

left - the dividend

right - the divisor

Returns:

the quotient

compareToImpl

public int compareToImpl(Number left,
 Number right)

Description copied from class: NumberMath

Compares two numbers.

Subclasses must implement this method according to type promotion hierarchy rules.

Specified by:

compareToImpl in class NumberMath

Parameters:
