http://issues.apache.org/bugzilla/show_bug.cgi?id=43656 Summary: ELSupport.coerceToType modifies BigDecimal Values Product: Tomcat 6 Version: 6.0.14 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Servlet & JSP API AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] If ELSupport.coerceToType is called with an BigDecimal instance as the first Parameter 'obj' and BigDecimal.class as type it should return the inputted value. Instead the BigDecimal is converted into a double and back into a BigDecimal which leads to a diffenent value. This happens in Line 228: if (BigInteger.class.equals(type)) { if (number instanceof BigDecimal) { return ((BigDecimal) number).toBigInteger(); } return BigInteger.valueOf(number.longValue()); // This leads to a different value. } Example: Run the Method with new BigDecimal("0.19"), BigDecimal.class as parameters. This should result in a BigDecimal with value 0.19. Instead i got 0.190000000000000002220446049250313080847263336181640625. The easiest solution is to compare the class of the object to coerce with the target class and return the inputted value if the are equal in ELSupport.coerceToType Method: public final static Object coerceToType(final Object obj, final Class type) throws IllegalArgumentException { if (type == null || Object.class.equals(type) || type.equals(obj.getClass())) { return obj; } ... -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
