Binary is the number system on which all digital computers are based. Therefore, it is important for developers to understand binary mathematics.
The purpose of the Bin2Dec Challenge is to provide practice and understanding of how binary calculations are done.
Bin2Dec allows the user to enter strings of up to 8 binary digits, 0 and 1, in any sequence and then display their decimal equivalent.
This task requires the developer implementing it to follow such constraints:
- Arrays cannot be used to store user-entered binary digits.
- Determining the decimal equivalent of a particular binary digit in a sequence must be calculated using a single mathematical function, such as the natural logarithm.
- The choice of function is up to you.
- The user may enter up to 8 binary digits in a single input field.
- The user must be notified if anything other than 0 or 1 has been entered.
- The user views the results in a single output field that contains the decimal (base 10) equivalent of the binary number entered.
- The user can enter a variable number of binary digits.
