             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}
