Rounding
High-precision currency values, unlike the Site Server 3.0 Commerce Edition integer values, have a fractional part. Because of this, Commerce Server 2000 rounds high precision currency values before writing them to the dictionary. This helps prevent situations where a fractional value might cause a total value that was not equal to the sum of displayed values.
The Commerce Server 2000 Software Development Kit (SDK) sample code for developing pipeline components includes monetary rounding functions for use in building components. See the files moneyinfo.h and moneyinfo.cpp in the SDK for more information.
