Re: No error for divide by zero

[Lars Müller <appgurulars@...>]

5/0 performs a floating-point division. IEEE 754 defines x/0 to be either inf (math.huge), -inf (-math.huge) or nan, depending on whether x is > 0, < 0 or = 0. Lua complies with this and doesn't throw an error.

5//0 on the other hand is an integer division. Lua is free to define what should happen here.

Hi,

Can anyone please tell me why we don't return an error for (5/0)? For (5//0), we return an error. I checked that we don't have any check for divisor value, but in luaV_idiv(), we check the divisor value.
