Method Detail

equals

public static final boolean equals(BigDecimal bd1,
             BigDecimal bd2)

Determines whether or not bd1 equals bd2.

Parameters:

bd1 -

bd2 -

Returns:

true if bd1 equals bd2, false otherwise.

lt

public static final boolean lt(BigDecimal bd1,
         BigDecimal bd2)

Determines whether or not bd1 isLessThan (<) bd2.

Parameters:

bd1 -

bd2 -

Returns:

true if bd1 isLessThan (<) bd2, false otherwise.

gt

public static final boolean gt(BigDecimal bd1,
         BigDecimal bd2)

Determines whether or not bd1 isGreaterThan (>) bd2.

Parameters:

bd1 -

bd2 -

Returns:

true if bd1 isGreaterThan (>) bd2, false otherwise.

lteq

public static final boolean lteq(BigDecimal bd1,
           BigDecimal bd2)

Determines whether or not bd1 isLessThanOrEqual (<=) to bd2.

Parameters:

bd1 -

bd2 -

Returns:

true if bd1 isLessThanOrEqual (<=) bd2, false otherwise.

gteq

public static final boolean gteq(BigDecimal bd1,
           BigDecimal bd2)

Determines whether or not bd1 isGreaterThanOrEqual (>=) to bd2.

Parameters:

bd1 -

bd2 -

Returns:

true if bd1 isGreaterThanOrEqual (>=) bd2, false otherwise.

invert

public static final BigDecimal invert(BigDecimal bdInput)

This function turns the BigDecimal into a negative number if it is positive, and vice-versa.

Parameters:

bdInput -

Returns:

The inverted BigDecimal input

manufactureBigDecimal

public static BigDecimal manufactureBigDecimal(String sInput)

Manufactures a BigDecimal with at 2 decimal places ('.00' as the default).

manufactureBigDecimal

public static BigDecimal manufactureBigDecimal(String sInput,
                               int scale)

Manufactures a BigDecimal with at least 'scale' decimal places.

manufactureBigDecimal

public static BigDecimal manufactureBigDecimal(int input)

toFormattedString

public static final String toFormattedString(BigDecimal bdInput)

Formats a BigDecimal like a dollar-formatted String, but without the dollar-sign. Thus, a number will have two decimal place digits, and commas separating every 3 digits.
