What is difference between sqrt and power

#1


I am using this to find roots of quadratic but roots are differing in both case when used sqrt(); function vs using pow(D,1/2) or pow(D,0.5) or pow(D,m) { m = 0.5 }

#2

Hey friend, sqrt(n) will give you square root of n which is (n)^1/2 whereas pow(n,m) will give you result of n^m.

#3

No I have set value of m to be 1/2 or 0.5 then also different result

#4

That’s because of data type, it can be float too. Need not necessary it to be int, instead of pow use sqrt it will be convenient for you :slight_smile:
