Main Content Sec.0.1 Numbering and coding systems Converting from decimal to binary Sec.0.1 Numbering and coding systems Converting from binary to decimal Sec.0.1 Numbering and coding systems Sec.0.1 Numbering and coding systems Converting number from base R to base 10 Sec.0.1 Numbering and coding systems Converting number from base 10 to base R When convert number from base 10 to base R, the integer and decimal fraction need to be calculated respectively. Dividing the integer by R repeatedly, keeping track of the remainders, this process continues until the quotient becomes zero. Sec.0.1 Numbering and coding systems Converting number from base 10 to base R Multiplying decimal by R repeatedly, keeping the integer, this process continues until the product is zero or depending on the request.
