I am having this number a=85.0093792283283 calculated in the code and I want to compare with another similar value something like this b=85.0093791964294. My question I just want to compare first 3 digit after the comma. Is there way to implement this in the example code?
if(a == b)
disp('Number are equal');
end

Here's one possibility
a=85.0093792283283;
b=85.0093791964294;
a = floor(a*10^3);
b = floor(b*10^3);
if a==b
disp('numbers are equal')
end
