Roberto Ierusalimschy f01c12c891 detail (cast to avoid mixing types in conditional expression) 2015-06-25 11:00:01 -03:00
Roberto Ierusalimschy a1415c0d72 bug in order NaN x int (tests must ensure that NaN does not get
converted to integer)
2015-06-09 12:53:35 -03:00
Roberto Ierusalimschy ed1fe28bb8 When comparing integers with floats, use float as common type when
possible (i.e., when integer fits in a float without losses); seems
to be more efficient in architectures with native support for used
Lua numbers
2015-06-02 16:11:24 -03:00

hook (as it may want to access local variables active by the end
of the function)
2015-05-22 14:48:19 -03:00
Roberto Ierusalimschy 6dc20ff293 'l <= r' for numbers has its own function, instead of using
