Real Scientific

WARNING: toRational needs to compute the Integer magnitude: 10^e. If applied to a huge exponent this could fill up all space and crash your program!

Avoid applying toRational (or realToFrac) to scientific numbers coming from an untrusted source and use toRealFloat instead. The latter guards against excessive space usage.
