  • retrieving a bytecode instruction associated with the floating point operation that can be compiled in a plurality of ways;

    determining whether the floating point operation can create a floating point underflow;

    compiling the bytecode instruction a first way;

    determining at runtime that a second way of compiling the bytecode instruction is desirable based on a predetermined criteria; and

    recompiling the bytecode instruction the second way.
