[antlr-interest] Problem with REAL and INT

[Imran A R (RBIN/EDM2)]

Hello all

	I have a antlr lexer for REAL and INT grammer  as follows.

	INT: (DIGITSET '.')=> REAL { $setType (REAL) ;}
	 | DIGITSET {$setType (INT) ;};

	protected DIGITSET: ('0'..'9')('0'..'9')*; 

	protected ALPHABETS :'a'..'z' |'A'..'Z';

	protected REAL: DIGITSET '.' DIGITSET;


	protected PARTIALSTRING : (ALPHABETS|'_') (ALPHABETS |'0'..'9'
| '_' )*;

	IDENT options{ testLiterals = true;}: PARTIALSTRING ( '.'
PARTIALSTRING )* ;

	
	
	I have a small parser as follows

	rule:(speed:"speed" EQUAL speed_val:REAL SEMI){

	printf("%s\n",speed->getText().c_str());

	printf("%s\n",speed_val->getText().c_str());
	
	};



	when I give speed = 19.2;, it is working fine. 

	but when I give 19 it is giving 

	"line 1:8: expecting REAL, found '19'"

	Can you please help me to solve this problem.

Thank you 
Imran
