roundn - Round to multiple of 10n
Syntax
roundn(x,n)
Description
roundn(x,n) rounds each
element of x to the nearest multiple of 10n. n must
be scalar, and integer-valued. For complex x, the
imaginary and real parts are rounded independently. For n
= 0, roundn gives the same result
as round. That is, roundn(x,0) == round(x).
Examples
Round pi to the nearest hundredth.
