What is the difference between float and double?

float has 23 mantissa bits + 1 hidden bit: log(224)÷log(10) = 7.22 digits
This precision loss could lead to greater truncation errors being accumulated when repeated calculations are done, e.g.
float a = 1.f / 81;
float b = 0;
for (int i = 0; i < 729; ++ i)
b += a;...

...have an array a which is constantly being updated. Let's say a = [1,2,3,4,5] . I need to make an exact duplicate copy of a and call it b . If a were to change to [6,7,8,9,10] , b should still be [1,2,3,4,5] . What is the best way to do this? I tried a for loop like:
