I\'m looking to create a fast hash table for values that

Answer 1

Some languages (C, Java 5) allow you to access the binary value of your floats. This way, you can extract the first N bits of the mantissa (ignoring the last few bits which cause the trouble during compare) and calculate the hash from that.
