Grammar A:
import "http://www.eclipse.org/emf/2002/Ecore" as ecore

Hold:
name=ID
scinots+=(SCIENTIFICNOTATION)
tests+=test;

SCIENTIFICNOTATION returns ecore::EDouble:
DOUBLE (('e'|'E') ('+'|'-')? INT)?;

DOUBLE returns ecore::EDouble:
('-')? INT ('.' INT)?;

Grammar B

RuleA:
'number' value=SCIENTIFICNOTATION;

when I write a formatter for File b: how would I format value if it was entered as number 1. 5 e-5
and I wanted it to be number 1.5 e-5

It is difficult to see or notice above, but what I want is no space around the period, if a decimal is used
