Hi
The Antlr grammar rule for double is as follows.
DOUBLE_LITERAL
: DIGIT+ ( '.' DIGIT* )? ( E [-+]? DIGIT+ )? D
;
fragment DIGIT : [0-9];
The converted Xtext grammar rule is :
DOUBLE_LITERAL:
DIGIT+ ( '.' DIGIT* )? ( E ('-'|'+')? DIGIT+ )? D
;
fragment DIGIT:
INT
;
@Override
terminal INT returns ecore::EInt:
('0'..'9');
Is this conversion correct?
The double values inserted in the following query in the editor seems errornous.
from purchase[price >= 30]#window.lossyFrequent(0.1,0.01) --double
select cardNo, price
insert into PotentialFraud ;
Thank you.
