Y = round(X,N) where N is the number of digits to the right (when positive) or left (negative).

Alternativly,

y = round(X*10)/10;

So i have two values

A = 1.69 and B = 1.8

A = 2.1 and B = 2.4

How do i show it that they are approximately equal without using round

are there any relational operators that i can use?

Either ismembertol or do it yourself by comparing the absolute difference against a tolerance limit:

abs(A-B)<tol
