The / function returns the value of the first argument divided by each of the subsequent arguments. Each of its arguments should be a numeric expression. Division is performed using the type of the arguments provided unless mixed mode arguments (integer and float) are used. In this case, the function return value and integer arguments are converted to floats after the first float argument has been encountered. By default, the dividend (the first argument) is automatically converted to a floating point number so that the result is a floating pointer number. The function set-auto-float-dividend can be used to control this behavior. If for example, the autofloat feature is disabled, the expression (/ 4 3 4.0) evaluates to 0.25 as opposed to 0.333333333 if this feature were enabled. This function returns a float if any of its arguments is a float, otherwise it returns an integer.
