round to nearest integer





real or complex matrix


integer value matrix (or complex matrix with integer real and imaginary part)


round(x) rounds the elements of x to the nearest integers.

In case of tie, this function rounds to infinities. That is, if x is positive and is halfway between two integers, then round(x) is rounded toward %inf. If x is negative and is halfway between two integers, then round(x) is rounded toward -%inf. In other words, if x is positive, then round(x) is equal to int(x+0.5), and if x is negative, then round(x) is equal to int(x-0.5)


// Notice that round(1.5)==2
round([1.3 1.5 1.7 2.5 3.7])
// Notice the result for x negative
// Notice that round(-1.5)==-2
round([-1.3 -1.5 -1.7 -2.5 -3.7])
round([2.2+%i*23, %pi*%i, -%i ])
