Range of decimal type in Calcite

[Hezhiqiang (Ransom)]

Hi all.
         What's the range of decimal data type in calcite?
         In SqlValidatorImpl. validateLiteral method , decimal range validate. 
It used a long value to validate it .
         Is it means decimal type max value in calcite is 922337203685477580.7
         And the min value in calcite is -922337203685477580.8
         And the scale value is 0.9223372036854775807
How to create a decimal literal like 99999999999999999999999999.999999999999 ?
