WebIf the float is beyond the boundaries of int (usually +/- 2.15e+9 = 2^31 on 32-bit platforms and +/- 9.22e+18 = 2^63 on 64-bit platforms), the result is undefined, since the float doesn't have enough precision to give an exact int result. No warning, not even a notice will be issued when this happens! Note: WebUse the bitwise OR operator ( ) to set a bit. number = 1UL << n; That will set the n th bit of number. n should be zero, if you want to set the 1 st bit and so on upto n-1, if you want to set the n th bit. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined ...
