IBM® SPSS Statistics does not consistently process double-precision, floating-point numbers

Due the manner in which modern computer processors manage double-precision, floating-point numbers, SPSS® Statistics can at times process what would normally present as single decimal values as multiple decimal values (up to 15 decimals). To resolve this issue, you must use computed numeric values as the criterion for logical expressions.
