Non integers number binary presentation

If the argument is 0x7ff0000000000000L, the result is positive infinity.

If the argument is 0xfff0000000000000L, the result is negative infinity.

If the argument is any value in the range 0x7ff0000000000001L through 0x7fffffffffffffffL or in the range 0xfff0000000000001L through 0xffffffffffffffffL, the result is a NaN. No IEEE 754 floating-point operation provided by Java can distinguish between two NaN values of the same type with different bit patterns. Distinct values of NaN are only distinguishable by use of the Double.doubleToRawLongBits method.

In all other cases, let s, e, and m be three values that can be computed from the argument:

int s = ((bits >> 63) == 0) ? 1 :
int e = (int)((bits >> 52) & 0x7ffL);
long m = (e == 0) ?
             (bits & 0xfffffffffffffL)
<< 1 :
             (bits & 0xfffffffffffffL) |

Then the floating-point result equals the value of the mathematical expression s·m·2e-1075.

The conversion can be done in reverse. For "normal" numbers x, let s be the sign of the value, e be floor(log2(x)) + 1075, and m be rounded from x/2e, and shift the values appropriately: s is the high bit, e is the next 11 bits, m is the remaining 52 bits.

Is it OK to Move Common ViewController Presentation Logic into Presentation Helper Classes
I know too little about your problem to provide the definite answer, but basically you have 2 options: - inheritance - composition I personally like inheritance although it is often stated you should choose composition over inheritance. Your helper sounds somewhat like composition, so that would be the preferred setup. With your specific problem as I understand it, inheritance would lead to a

Dynamic number of integers using pointers and scanf()
You can use it if you keep a pointer to the original data: mem_p = (int *) calloc(num_el, sizeof(int)); int* p = mem_p ; printf("Enter %d numbers", num_el); for(i = 0; i < num_el; i++) { scanf("%d", p++); } and then: p = mem_p ; printf("The numbers entered was: "); for(i = 0; i < num_el; i++) { printf("%d ", *p++ ); } You incremented the only pointer pointing to the entire arr

Accepting a known number of integers on a single line in java
If you only have to accept two integer numbers you could do something like this: String input = System.console().readLine(); //"10 20" //String input = "10 20"; String[] intsAsString = input.split(" "); int a = Integer.parseInt(intsAsString[0]; int b = Integer.parseInt(intsAsString[1]); intsAsString is an array, in simple terms, that means it stores n-strings in one variable. (Thats very simpli
