ROUND

NAME

round - Standart rounding of a number.

SYNOPSIS

round(number[, decimal:integer])

DESCRIPTION

This mathematical function returns the nearest integer of the argument. It does not take the sign into account.

from version 5.167 the parameter specidfy the number of decimal from 0 to 10.

PARAMETERS

number
Specify the number (float) used as argument for the round function.

RETURN

The nearest integer of the argument.

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=\[4,-4,2\].));

round(3.1415926535, decimal:2); return 3.14

round([5.5, -5.5,3.1415926535, -3.99], decimal:2); return res=[5.5,-5.5,3.14,-3.99].

round([5.5, -5.5], [3.1415926535, -3.99], decimal:0);
round([5.5, -5.5,3.1415926535, -3.99], decimal:2);

return [[6,-6],[3,-4]][5.5,-5.5,3.14,-3.99]



round(null, decimal:2);
round(undefined, decimal:2);
round(true, decimal:2);
round(false, decimal:2);
round(3.14159265351234568, decimal:10);

return 00103.14159265



a=round({"x1" : [5.5, -5.5,3.1415926535, -3.99], "y1": 2.7182818}, decimal:2);
a.x1;a.y1 

return [5.5,-5.5,3.14,-3.99]2.72
