In computer science, it is often more convenient to use different number systems, especially base-2 (binary), base-8 (octal) and Zbase-16 (hexadecimal). Other number systems use different bases. This lesson is a precursor to looking at several other number systems important to computing, especially binary and hexadecimal. The radix in the parseInt( ) function can be any number 2–36 and does not default to Purplemath. , 0 and 1. Definition: In digital electronics, the number system is used for representing the information. Examples: 10101 2 = 10101B = 1×2 4 +0×2 3 +1×2 2 +0×2 1 +1×2 0 = 16+4+1= 21. Each digit is referred to as a bit. This simple tool allows you to convert a same number between its representations under different number systems. ; one gets the idea. radix in binary number system
