Roberto Ierusalimschy 483c2ccd0f avoid using raw representation of numbers for hashing, as number may 
not use all its space (e.g., long double can have sizeof=12 but
use only 10 bytes)
 2013-06-25 15:57:18 -03:00
Roberto Ierusalimschy 982aa7058f 'luaL_len' returns lua_Integer instead of 'int' 2013-06-25 11:05:26 -03:00
Roberto Ierusalimschy 80cdf39d0e avoid using 'modf' in the implementation of 'math.modf', to avoid 
problems with 'double*'. (When using 'float' as lua_Number,
'float*' is not compatible with 'double*'...)
 2013-06-25 11:02:18 -03:00
Roberto Ierusalimschy 45f3797a5b 'long' may have more than 32 bits in some machines; use 'int' for 
small lua_Integer unless necessary to use 'long'

numerical value

Roberto Ierusalimschy 453450d687 new macro 'l_floor' (allows 'floorf' even when other math operations

Roberto Ierusalimschy 130c0e40e0 new constant 'MAX_SIZE', distinct from 'MAX_SIZET', for sizes visible 
from Lua; these must fit in a lua_Integer
