Since the argument of drawLine is image.Point (a structure with x,y as integers), the floating point number is cast to an integer.

diagram-as-code/internal/types/link.go

Lines 116 to 119 in cc6f6ce

    
           a := arrowPt.Mul(i) 
        
           b := a.Add(at1.Mul(al - i)).Div(al) 
        
           c := a.Add(at2.Mul(al - i)).Div(al) 
        
           l.drawLine(img, b, c)

Considering extensibility, an option is to create a Point structure with x and y as floating point numbers.
