How to repeat: Run "./mysql-test-run.pl fulltext" on a windows machine. The value returned from MATCH is returned as a real with macimum number of decimals. But in the code only a float is used to return the match value from 'ft_boolean_find_relevance' and 'ft_nlq_find_relevance' Suggested fix: Limit the number of decimals used when returning the match value to FLT_DIG, which normally is "6".
