--------------------------------------
Summary: strange result in toString function with bigdecimal type
Key: CALCITE-4346
URL: https://issues.apache.org/jira/browse/CALCITE-4346
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Zhixiong Chen
In SqlFunctions the toString function with BigDecimal type will replace 0.1
with .1 .
But why is this ?
{code:java}
public static String toString(BigDecimal x) {
final String s = x.toString();
if (s.equals("0")) {
return s;
} else if (s.startsWith("0.")) {
// we want ".1" not "0.1"
return s.substring(1);
} else if (s.startsWith("-0.")) {
// we want "-.1" not "-0.1"
return "-" + s.substring(2);
} else {
{code}
