Approximate Equality in Matlab

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 ?

Answer 1

[Walter Roberson]

if abs(A-B) < tolerance

See also ismembertol()

There is no operator symbol for approximate equality -- no A?=B or anything like that.

Answer 2

[David Hill]

tol=.2;%whatever you want
abs(B-A)<tol;
