Extended Description

The difference in behavior between these two examples seems
very wrong to me. 
If it's a bug, it should be fixed. If it's part of the language
definition, the definition is wrong and should be fixed.
cat bugparser.sac
int main()
{
  y = 0.0012;
  StdIO::print(y);
  y = .0012;
  StdIO::print(y);
  return(0);
}

I think it's a parser bug:
cat bugparser.sac 
int main()
{
  x = 0.0012;
  StdIO::print(x);
  y = .0012;
  StdIO::print(y);
  z = _sub_SxS_( x, y);
  StdIO::print(z);
  return(0);
}
sac@rattler:~/sac/testsuite/optimizations/pwlf$ sac2c bugparser.sac -v1
./bugparser.sac 1 error: All instances of "main" contain type errors
