MATLAB: Taking the nearest decimals possible

decimal

Hi,

I have a query

i have 2 number

1] 1.6778

2] 2.032

How do i take the number 1.6778 to 1.7 ( nearest value)

and 2.032 to 2.0 ?

Kindly help

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;

I wrote a little utility function for my own use a while back to do just that:

expstr = @(x) [x*10.^floor(1-log10(abs(x)))  floor(log10(abs(x)))];
a = 12.345;
b = expstr(a)
b =
    1.2345    1.0000

I leave the rest to you.

Have you considered using built-in function 'round'?

Then you can just do:

if round(x,3) == round(y,3)
    ...
end
