Method Detail

round

public static double round(double dValue)

round

public static Double round(Double dValue,
                           int fraction)

Round a double value to a fraction of the given precision.

Parameters:

dValue - the double value to be rounded

fraction - is an integer value in the range 1..m_dFractionMultiplier, e.g. if m_dFractionMultiplier=100,0 a value of fraction=50 will round to 50 cents.

Returns:

compare

public static int compare(double d1,
                          double d2)

Compare two currency values rounded to the defined currency precision

Parameters:

d1 - fist double value

d2 - second double value

Returns:

the value 0 if d1 is numerically equal to d2
a value less than 0 if d1 is numerically less than d2;
and a value greater than 0 if d1 is numerically greater than d2.
