How many binary bits are required to represent decimal numbers between 300 and 400

SOURCE: programming in c

To convert numbers you can use the printf() function
printf("%d", x'FF') hex to decimal
printf("%o", x'FF') hex to octal

If you want to save the value in another variables use sprintf
e.g

a = x'FF';
b = sprintf("%d",a)

SOURCE: Write a program that requires a positive number

Here the code in C#:

public static double whole(double num)
{
double temp=0;
do { num--; temp++; } while (num > 0);
return (temp - 1);
}
static void Main(string[] args)
{
double num, temp;
int count1=0, count2=0;
num = double.Parse(Console.ReadLine());
if (num > 0)
{
temp = num;
do { temp /= 10; count1++; } while (temp > 1);
do { num *= 10; count2++; } while (num - 1 != whole(num));
Console.Write("Left=");
Console.WriteLine(count1);
Console.Write("Right=");
Console.WriteLine(count2);
}
else
{
Console.WriteLine("Positive only!");
}
}
You can translate in to other language.
But this works only for number less then 11 digit or it's very slow.
Rate me please, thanks.

SOURCE: A bit represents how many digits in binary code

1 digit is one bit, either 1 or zero in binary, so 8 bits shows 8 digits (10001011)

How about 4 thumbs??

Greetings,

Use the built-in windows calculator. (Start/Programs/Accessories/Calculator or Start/Run then type calc.exe and press Enter)

At the top click View then choose Programmer (for Win7) or Scientific mode for XP or Vista to convert.
