nl_tokens: With this unused function we always make sure we have an unsigned integer value but it s not absolutely necessary . We re only interested in the integer value when we perform addition or write the value to our buffer . We do not do this within Murmur s mix function . I m leaving it in place for a benchmark where I can gauge the cost of >>> 0 .
pl_tokens: function fmix32_pure ( hash ) { hash = ( hash ^ ( hash >>> 16 ) ) >>> 0 hash = multiply ( hash , 0x85ebca6b ) hash = ( hash ^ ( <mask> >>> 13 ) ) >>> 0 hash = multiply ( hash , 0xc2b2ae35 ) hash = ( hash ^ ( hash >>> 16 ) ) >>> 0 return hash }
