scol value

#define MTOI(val) ((val)>>1)
#define MTOP(val) ((val)>>1)
#define ITOM(val) ((val)<<1)
#define PTOM(val) (((val)<<1)+1)
_inline float MTOF(int val) {    return *(float*)&(val);    }
_inline int   FTOM(float val) {    return ((*(int*)&(val)) & 0xfffffffe);    }

these operation >> << &fffffffe

wouldn't it decrease  the numbers's precision?

How scol deal with that.

Hi kenshin!

yes this decrease the float precision ...

but the last bit is used by the VM to determinate the value type
