FDIM
NAME
fdim - This function returns the positive difference between the 2 var chosen by the user.
SYNOPSIS
fdim (number x,number y)
DESCRIPTION
This mathematical function returns the positive difference between x and y. Y has to be equal or higher than x, otherwise it will return zero. It gives the answer to Y-X.
PARAMETERS
- number
- Specifies the two numbers (float) used as argument for the fdim function.
RETURN
- The positive difference between x and y.
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={_{fdim(3,10);}}.),q(res=7.));
test(q(res={_{fdim(10,3);}}.),q(res=0.));
With floats:
test(q(res={_{fdim(2.5,3);}}.),q(res=.5.));
One can use this function with another variable:
test(q(res={_{
%include "/includes/extenso.sn";
a=3;
fdim(a,4);
}}.),
q(res=1.));
With a trigonometric function:
test(q(res={_{
%include "/includes/extenso.sn";
a=cos(0);
fdim(0,a);
}}.),
q(res=1.));
With negative numbers:
test(q(res={_{fdim(-3,2);}}.),q(res=5.));
One can also consider the limits:
test(q(res={_{fdim(-INF,INF);}}.),q(res=0.));
With an array, it simply considers its number of elements:
test(q(res={_{fdim(1,[1,2]);}}.),q(res=1.));
