Scientific (exponential) notation #52

Open j3ns opened 1 year ago

j3ns commented 1 year ago

Allow numbers to be written in queries in scientific (exponential) notation, e.g. 1e6 instead of 1000000.

Lexing numbers in this plugin seems to be too simplified at the moment compared to the Neo4j (v5.3) Cypher parser. Please implement a pragmatic solution which allows the scientific notation and hex numbers.

Hi @j3ns, thank you for pointing me in the right direction with the link to Neo4j's javacc file. I ported the definition of decimal doubles to this plugin. I also added token definitions for hex and octal numbers.
