Roberto Ierusalimschy 319ccfefbc computations in numerical for loop must avoid overflows too 2015-07-04 13:31:03 -03:00
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
Roberto Ierusalimschy d39bb51faa bug: interpreter cannot pop activation frame before calling return 
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 
'not (r < l)' (seems to be slightly more efficient)
 2015-05-20 15:19:11 -03:00

representation)
 2015-05-20 13:22:55 -03:00

Roberto Ierusalimschy 4ba0cb4580 always use macros to operate on lua_Numbers 2015-03-07 16:30:16 -03:00
Roberto Ierusalimschy 6408bc0b7f new macros 'chgfltvalue'/'chgivalue' (numerical for loop does

 2015-03-02 13:04:52 -03:00
Roberto Ierusalimschy 81245b1ad5 'numisinteger' (for table keys) replaced by 'luaV_tointeger' (old

 2015-01-16 14:54:37 -02:00
Roberto Ierusalimschy 50e2eb8954 change in macro 'vmcase', avoding code inside it. (Code inside the 
macro harms tools such as debuggers.)
 2014-12-27 18:30:38 -02:00
Roberto Ierusalimschy 2b83711fba new macro 'nvalue' (to convert an object to a float when we know

use floor intead of requiring an exact integral value)
 2014-11-03 18:07:47 -02:00

Roberto Ierusalimschy 3a15c7ce43 size for array part of a table ('sizearray') changed from 'int' to 
'unsigned int', which allows twice as many elements in the array part
 2014-09-04 15:15:29 -03:00
Roberto Ierusalimschy d861706620 new macro 'cvt2num' to better control whether strings are convertible 
to numbers
 2014-07-30 11:42:44 -03:00

to strings
 2014-07-30 11:00:14 -03:00

(no need to convert to 'GCObject')
 2014-07-21 13:02:10 -03:00
Roberto Ierusalimschy ca41b43f53 type 'TString' refers directly to the structure inside the union 
(union used only for size purposes)
 2014-07-18 10:36:14 -03:00
Roberto Ierusalimschy 8bb272a3e3 new conversion float->integer: conversion is valid only when 
float has an exact representation as an integer
 2014-07-17 09:30:53 -03:00
Roberto Ierusalimschy b9dcf9974d detail (typos in comments) 2014-06-30 16:48:08 -03:00

Roberto Ierusalimschy c98f195eb9 function 'luaV_numtointeger' changed to a global macro 
'lua_numtointeger' (tricky, small, and useful in several places)
 2014-05-26 14:10:22 -03:00
