EXAMPLES

Note: In the followings examples, the _ between the { should be removed to make it work.

One can use this function with integers:

test(q(res={_{round(-5);}}.),q(res=-5.));

With floats (negative or positive):

test(q(res={_{round(-4.5);}}.),q(res=-5.));
test(q(res={_{round(4.5);}}.),q(res=5.));

With another variable:

test(q(res={_{
%include "/includes/extenso.sn";
a=2.6;
round(a);
}}.),
q(res=3.));

With a trigonometric function:

test(q(res={_{
%include "/includes/extenso.sn";
a=cos(PI);
round(a);
}}.),
q(res=-1.));

With an array:

test(q(res={_{round(4.3,-4.3,1.5);}}.),q(res=\[4,-4,2\].));
