Summary: float multiply towards zero fails

Initial Comment:
When multiplying a float with 0.8 again and again the value does not result in zero, but overflows into something big. E.g.

float mult(float x) { return x * 0.8); }

ASSERT ( mult (1e-38) < 1.0); // fails

This happens for mcs51, but I haven't tested others yet.
