HYPOT
NAME
hypot - This function computes the hypothenuse of 2 var chosen by the user.
SYNOPSIS
hypot(number x,number y)
DESCRIPTION
This mathematical function allows the user to compute the square root of the sum of the squares of x and y. It is equivalent to the longest side of a right-angled triangle with sides of lenght x and y, starting at (0,0).
PARAMETERS
- number
- Specifies the two numbers (float) used as argument for the hypot function.
RETURN
- The hypothenuse of x and y.
EXAMPLES
One can use this function with integers:
test(q(res=<{hypot(3,4);}>.),q(res=5.));
With floats:
test(q(res=<{hypot(2.5,3);}>.),q(res=3.90512.));
One can use this function with another variable:
test(q(res=<{
%include "/includes/extenso.sn";
a=3;
hypot(a,a);
}>.),
q(res=4.24264.));
With a trigonometric function:
test(q(res=<{
%include "/includes/extenso.sn";
a=cos(0);
hypot(a,1);
}>.),
q(res=1.41421.));
With negative numbers :
test(q(res=<{hypot(-2,2);}>.),q(res=2.82843.));
One can also consider the limits:
test(q(res=<{hypot(-INF,INF);}>.),q(res=0.));
With an array, it simply considers its number of elements:
test(q(res=<{hypot(2,[1,2]);}>.),q(res=2.82843.))
