Extended Description

Specifically, this example fails on the line assigning to z:
 cat scientificnotationbug.sac
int main()
{
  x = 1.2e+3;
  StdIO::print();
  y = 1.2e-3;
  StdIO::print(y);
  z = 1.2e3;  // This should work.
  StdIO::print(z);
  return(0);
}

This did work, once upon a time, I believe.
