Float.floatToRawIntBits (in Java1.4) gives the raw float bits without normalization (like *(int*)&floatvar would in C). Since it doesn't do normalization of NaN values, it's faster (and hopefully optimized to a simple inline machine instruction by the JVM).
On my Pentium4, using floatToRawIntBits is over 5 times as fast as floatToIntBits. That can really add up in something like Similarity.floatToByte() for encoding norms, especially if used as a way to compress an array of float during query time as suggested by Doug. -Yonik Now hiring -- http://forms.cnet.com/slink?231706 --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
