relativeChange

Creates a Percentage which represents the relative change of this number to another number. Calculations using it won't be rounded. Example:

1.changeOf(5) // 400%

Or using the infix notation:

1 changeOf 5

When this number is zero, an IllegalArgumentException exception is thrown as the relative change for this case is not defined.

When both numbers are zero, a Percentage(0) is returned meaning no change happened instead of returning a Percentage(NaN) (which would happen as a result o dividing 0 by 0, both computationally and mathematically).

Parameters

Throws

Creates a Percentage which represents the relative change of this number to another number. Calculations using it will be rounded. Example:

1.changeOf(5, 2) // 400%

When this number is zero, an IllegalArgumentException exception is thrown as the relative change for this case is not defined.

When both numbers are zero, a Percentage(0) is returned meaning no change happened instead of returning a Percentage(NaN) (which would happen as a result o dividing 0 by 0, both computationally and mathematically).

Parameters

Throws

Creates a Percentage which represents the relative change of this number to another number. Calculations using it will be rounded. Example:

1.changeOf(5, Rounding.to(2, RoundingMode.HALF_DOWN)) // 400%

When this number is zero, an IllegalArgumentException exception is thrown as the relative change for this case is not defined.

When both numbers are zero, a Percentage(0) is returned meaning no change happened instead of returning a Percentage(NaN) (which would happen as a result o dividing 0 by 0, both computationally and mathematically).
