INFORMATION

DECIMAL TO BASE 7 CONVERSION

WHOLE NUMBERS

We apply the following rules to convert a decimal number to base 7.

  • We divide the decimal number by 7 repeatedly until the quotient becomes 0.
  • Starting at the least significant digit, we write the remainders in the same order of divisions.
Decimal to base 7 conversion example

For example, to convert decimal 93 to base 7, we divide 93 by 7 repeatedly until the quotient becomes 0.

When we divide 93 by 7, the quotient is 13 and the remainder is 2. Thus, 2 is the least significant digit of the base 7 equivalent. We continue the algorithm with 13. When we divide 13 by 7, the quotient is 1 and the remainder is 6. Then 6 is the second least significant digit of the base 7 number. Finally, we divide 1 by 7. When we do this operation, the quotient is 0 and the remainder is 1. Because the quotient is 0, we stop the procedure. Then we write the last remainder to the most significant digit of the base 7 number. To sum up, the base 7 representation of 93 is 162.

(93)10 = (162)7

DECIMAL NUMBERS

In case, the decimal number is not an integer, we can convert the whole number and fractional parts separately and add up base 7 equivalents.

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

  • We multiply the fractional part by 7 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 7 number. We continue with the fractional part of the product.
 

For example, to convert 93.71 to base 7, we multiply the fractional part by 7 repeatedly until we find an integer.

  • 0.71 × 7 = 4.97
  • 0.97 × 7 = 6.79
  • 0.79 × 7 = 5.53
  • .......................
 
Whole number and fractional parts

The fractional part of 93.71 is 0.71. When we multiply 0.71 by 7, the result is 4.97. The integer part of 4.97 is 4. Thus we write 4 to the first digit on the RHS of the radix point.

0.4

We continue with the fractional part of 4.97. When we multiply 0.97 by 7, the result is 6.79. We write the integer part of 6.79 to the next digit.

0.46

The fractional part of 6.79 is 0.79. Therefore, we continue with this number. The product of 0.79 and 7 is equal to 5.53. We write the integer part to the next digit.

(0.71)10 = (0.465...)7

Base 7 representation of 93.71 is equal to the sum of base 7 representations of 93 and 0.71. Thus, decimal 93.71 is equal to 162.465... in base 7.

(93.71)10 = (93)10 + (0.71)10

= (162)7 + (0.465...)7

= (162.465...)7
