Editing Octal (section)

====Method of successive multiplication by 8====
To convert a decimal fraction to octal, multiply by 8; the integer part of the result is the first digit of the octal fraction. Repeat the process with the fractional part of the result, until it is null or within acceptable error bounds.

Example: Convert 0.1640625 to octal:
:0.1640625 × 8 = 1.3125 = '''1''' + 0.3125
:0.3125 × 8 = 2.5 = '''2''' + 0.5
:0.5 × 8 = 4.0 = '''4''' + 0
Therefore, 0.1640625<sub>10</sub> = 0.124<sub>8</sub>.

These two methods can be combined to handle decimal numbers with both integer and fractional parts, using the first on the integer part and the second on the fractional part.
