How do you round to the nearest number in Matlab?

How do you round to the nearest number in Matlab?

Y = round( X ) rounds each element of X to the nearest integer. In the case of a tie, where an element has a fractional part of exactly 0.5 , the round function rounds away from zero to the integer with larger magnitude. Y = round( X , N ) rounds to N digits: N > 0 : round to N digits to the right of the decimal point.

How do you round to the nearest 10 in Matlab?

How to round up to the next 10
