# round

round to nearest integer

### Syntax

y=round(x)

### Arguments

- x
real or complex matrix

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

### Description

`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)`

### Examples

// 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 ])
