DECIMAL TO BASE 15 CONVERSION

WHOLE NUMBERS

We apply the following rules to convert a decimal number to base 15.

• We divide the decimal number by 15 repeatedly until the quotient becomes 0.
• Starting at the least significant digit, we write the remainders in the same order of divisions.

For example, to convert decimal 856 to base 15, we divide 856 by 15 repeatedly until the quotient becomes 0.

When we divide 856 by 15, the quotient is 57 and the remainder is 1. Thus, 1 is the least significant digit of the base 15 equivalent. We continue the algorithm with 57. When we divide 57 by 15, the quotient is 3 and the remainder is 12. Because 12 is equivalent to C in base 15, we write C to the second least significant digit of the base. Finally, we divide 3 by 15. When we do this operation, the quotient is 0 and the remainder is 3. Because the quotient is 0, we stop the procedure. Then we write the last remainder to the most significant digit of the base 15 number. To sum up, the base 15 representation of 856 is 3C1.

(856)₁₀ = (3C1)₁₅

DECIMAL NUMBERS

In case, the decimal number is not an integer, we can convert the whole number and fractional parts separately and add the base 15 equivalents up.

To convert the fractional part of a decimal number, we apply the following rules.

• We multiply the fractional part by 15 repeatedly until the product becomes an integer or the number of significant digits is sufficient for our calculations.
• At each step, we write the integer part of the rightmost digit to the fractional part of the base 15 number. We continue with the fractional part of the product.

For example, to convert 856.16 to base 15, we multiply the fractional part by 15 repeatedly until we find an integer.

• 0.16 × 15 = 2.4
• 0.4 × 15 = 6

The fractional part of 856.16 is 0.16. When we multiply 0.16 by 15, the result is 2.4. The integer part of 2.4 is 2. Thus we write 2 to the first digit on the RHS of the radix point.

0.2

We continue with the fractional part of 2.4. When we multiply 0.4 by 15, the result is 6. Because 6 is an integer we write it to the next digit of the base 15 number and stop multiplications.

(0.16)₁₀ = (0.26)₁₅

Base 15 representation of 856.16 is equal to the sum of base 15 representations of 856 and 0.16. Thus, decimal 856.16 is equal to 3C1.16 in base 15.

(856.16)₁₀ = (856)₁₀ + (0.16)₁₀

= (3C1)₁₅ + (0.16)₁₅

= (3C1.26)₁₅
