FractionalConversion

public FractionalConversion(java.lang.String fromUnit,
                            java.lang.String fromUnitAbbr,
                            java.lang.String toUnit,

Method Detail

convertValue

public double convertValue(double value,
                           java.lang.String pFromUnit)

Description copied from class: Conversion

Converts a value for you are returns the answer.

Specified by:

convertValue in class Conversion

Parameters:

value - double value you want to convert

pFromUnit - Unit that you want to convert from

Returns:

answer If the fromUnit does not match the classes from unit, then it is assumed that you are converting the other way ex. System.out.println(conversion.convertValue(17, conversion.getFromUnit()));

convertValue

public java.lang.String convertValue(java.math.BigInteger numerator,
                                     java.math.BigInteger denominator,
                                     java.lang.String pFromUnit)

Description copied from class: Conversion

Converts a value represented by a numerator and denominator, returning a String representation of the result

Specified by:

convertValue in class Conversion

Parameters:

numerator -

denominator -

pFromUnit -

Returns:

multiply

public java.lang.String multiply(Conversion byConversion)

Description copied from class: Conversion

Multiply this conversion by the passed in conversion

Specified by:

multiply in class Conversion

Parameters:

byConversion - Conversion you are multiplying by

Returns:

String representation of the value. I know this is a bit hokey, but it allows me to pass this back into the create method and generate another conversion if need be. This String number can be a fraction, decimal or integer.

divide

public java.lang.String divide(Conversion byConversion)

Description copied from class: Conversion

Divide this conversion by the passed in conversion

Specified by:

divide in class Conversion

Parameters:

byConversion - Conversion you are dividing by

Returns:

String representation of the value. I know this is a bit hokey, but it allows me to pass this back into the create method and generate another conversion if need be. This String number can be a fraction, decimal or integer.

getFromToBottomFactor

public java.math.BigInteger getFromToBottomFactor()
