Power factor is truepower divide by apparent power.
First, review the definition of an Armstrong, or narcissistic, number:"...is a number that is the sum of its own digits each raised to the power of the number of digits."So, you need to count the digits (to know what power to use), and extract the individual digits. This can be done in several ways; for example, you might convert the number to a string. In Java:String numberAsString = "" + number;Now it should be easy to figure out the length of the String (use the .length() method), and to extract the individual digits - check the methods available for strings. Then you need to convert the digits back to numeric data.Another way is to get one digit at a time, starting from the right, using the "%" operator.For example, 153 % 10 is equal to 3. Divide the number, 153, by 10 (integer division), then repeat to get the remaining digits. You might store the digits to an array.First, review the definition of an Armstrong, or narcissistic, number:"...is a number that is the sum of its own digits each raised to the power of the number of digits."So, you need to count the digits (to know what power to use), and extract the individual digits.

When multiplying by a power of ten the digits of the number move left the same number of place value columns as the power. When dividing by a power of ten the digits of the number move right the same number of place value columns as the power. As this is awkward to do with pencil and paper, the effect on the position of the decimal point is used instead: To multiply by a power of ten the decimal point is moved right the same number of digits as the power of 10; To divide by a power of ten the decimal point is moved left the same number of digits as the power of 10; If there are insufficient digits to do the moving zeros (0) are inserted as necessary.
Armstrong numbers are the sum of their own digits to the power of the number of digits.

Decimal to fraction: The part to the left of the point is unchanged. To the right, count the number of digits, and the fractional part is the actual digits to the right, divided by 10 to the power number of digits. Example: 34.567 : 34 remains the same . There are 3 digits after the point, so 103 =1000 and the part after the point is equivalent to 567/1000, and the complete number is therefore "34 and 567/1000". For fractional to decimal, just divide the top number by the bottom: example 4 and 3/5 (" four and three fifths) divide the 3 by 5 and get 0.6 so the result is 4.6
