SuJinpei opened a new pull request #1818: [TRAFODION-3262] Insert float to numeric(19,0) lost precision for some case URL: https://github.com/apache/trafodion/pull/1818 root cause: when the target numeric type's precision is bigger than 18, the source float or double data will first be converted to char string which will call the double_to_char function, then transfer to the server. original double_to_char only keep 'precision' significant digits. In this case, the caller provides the precision with 6 for float datatype, so last 2 digits' precision lost. solution: now, the 'precision' parameter means the number of digits after the decimal point which is the caller really meant to do. To prevent precision lost, the conversion will fail if the caller doesn't provide enough space to receive the result. verify: no new issue was found by running coast to verify the fix.
