10 compliment

Question

What is 10 compliment of decimal number 2056.064 ?

I know the method 10 compliment = 9 compliment + 1

Now 9 compliment = 9999.999 - (2056.064)= 7943.935

Now 10 complimnet = 9 compliment +1

= 7943.936   or 7944.935 ?

10 complimnet = 9 compliment +1  it is valid only for integers..
for fractional x
first find no of significant digits after decimal.
let call it as y.
then find 9s complement  x.
add 10^(-n) to the 9s complement of x.

Answer 1

see if u take 10 complement of a no x that means x + complement (x) = 10^n..
where n is no of digits in integer part of (x)..
that is one way to verify..
in case of 2056.064 complement is nothing but 10^4-2056.064 i.e. 7943.936.
correct me if i wrong.

Okay sir :) yes i read that in morris manno

(R compliment ) compliment is 10^n - number

where n is no  digit in number (Integer part )

And suppose if i want to find diminished compliement (R-1 )then it is 10^n- 10^-m- number

where n is no of digit in integer part

m is the number of digit in fractional part
