Output:

Real results:rp=4.2; rn=4.2; cp3i4=5.0; cn3i4=5.0; 

2 Excel

=ABS(-4.2)
// 4.2
=ABS(5)
// 5
=ABS(-5)
// 5

3 JavaScript

var a=Math.abs(-4.2); // 4.2
var b=Math.abs(5); // 5
var c=Math.abs(-5); // 5
var d=Math.abs(null); // 0
var e=Math.abs("Hello"); // NaN

4 PHP

$a = abs(-4.2); // 4.2;
$b = abs(5);   // 5;
$c = abs(-5);  // 5;

5 Python

a = abs(-4.2); # 4.2;
b = abs(5);   # 5;
c = abs(-5);  # 5;
