How to round decimal number to 5 places?

I am working on Coordinate system based on GPS and have got latlong points to 7digit place ..when i convert them to radian, they expand upto 9 place. My code requires only use upto 5 digits for the calculations. I tried using "round" commands but it says too many input arguments. Can anyone help me with this please.

It is easy to create your own version in an anonymous function:

roundn = @(x,n) round(x.*10.^n)./10.^n;

pi_5 = roundn(pi,5)

produces:

pi_5 =

                     3.14159

If you know you always want to round the radian angle to 5 decimal places, change the function to:

round5 = @(x) round(x.*10.^5)./10.^5;

you can do like this

>> a=1.12345678

a =

   1.123456780000000

>> sprintf('%0.5f', a)

ans =

1.12346

The only problem with that approach is that the output is a string, not a double-precision number.

X = str2double(ans) it can solve the problem

I just tried using str2double(ans) , but it ends up displaying all the zeros at the end again
