round

round to nearest integer

Calling Sequence

`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 ])```

• int — round towards zero
• floor — round down
• ceil — round up
