To call a function you must use the following protocol: first, the function to be called is pushed onto the stack; then, the arguments to the function are pushed in direct order; that is, the first argument is pushed first. A Field permits widening conversions to occur during a get or set access operation, but throws an IllegalArgumentException if a narrowing conversion would occur. Janes | The latest defence and security news from Janes - the trusted source for defence intelligence How could I convert it into a double? Please note that setting the exception bit for failbit is inappropriate for this use case. If the converted value would be out of the range of representable values by a double, it causes undefined behavior. lua_call [-(nargs + 1), +nresults, e] void lua_call (lua_State *L, int nargs, int nresults); Calls a function.

Firstly, there are integers and floating-point numbers. Ok, I have a char that is a number. Integers are always whole numbers, such as 0, 1, -32, 42 and 1337.On the other hand, floating-point numbers can have a fractional part: 0, 1, -32.1, 42.7 and 123.456788 are all valid floating-point numbers..

Floating point numbers are usually implemented using double in C; information about the precision and internal representation of floating point numbers for the machine on which your program is running is available in sys.float_info.

Any bitwise operator (here I've done a bitwise or, but you could also do double negation as in an earlier answer or a bit shift) will convert the value to a 32 bit integer, and most of them will convert to a signed integer. inttoptr and ptrtoint instructions have the same semantics as for integral (i.e. ToString(Int32, Int32) Converts the value of a 32-bit signed integer to its equivalent string representation in a specified base. But if the int, or other longs are your only input, and your method can be modified, I would suggest this approach.
