Square root basic approach

I am not able to understand inc=inc/10; please explain me this in the program

suppose we have to find square root of 40
then firstly we have to find the integer value of sqrt(40)
so we increment the ans with 1 and hence ans = 6

then to get more precise value
we increment ans with 0.1 (inc=inc/10)
so we check for 6.1 then 6.2 then 6.3
so now our ans is 6.3
to get more accurate ans

we again decrease inc to 0.01 (inc=inc/10)

in square root we can give the inc value and divide it but if the no already giving like 2 and I have to divide it by 6 it willgie 0.3333 I want to find it how can I do that what’s the method for that

by inc method I understand I am just asking the no already giving we don’t have to use inc just we have to divide it and get the accurate and wahterever it will be

like 2%6=0.3333 how can I find that

by inc method I understand I am just asking the no already giving we don’t have to use inc just we have to divide it and get the accurate and wahterever it will be

i didn’t understand what you are saying
