/ Function
Syntax:
/ number → reciprocal
/ numerator &rest denominators+ → quotient
Arguments and Values:
number, denominator—a non-zero number .
numerator, quotient, reciprocal—a number .
Description:
The function / performs division or reciprocation.
If no denominators are supplied, the function / returns the reciprocal of number.
If at least one denominator is supplied, the function / divides the numerator by all of the denominators and returns the resulting quotient.
If each argument is either an integer or a ratio, and the result is not an integer , then it is a ratio.
The function / performs necessary type conversions.
If any argument is a float then the rules of floating-point contagion apply; see Section 12.1.4 (Floating-point Computations).
Examples:
(/ 12 4) → 3
(/ 13 4) → 13/4
(/ -8) → -1/8
(/ 3 4 5) → 3/20
(/ 0.5) → 2.0
(/ 20 5) → 4
(/ 5 20) → 1/4
(/ 60 -2 3 5.0) → -2.0
(/ 2 #c(2 2)) → #C(1/2 -1/2)
Exceptional Situations:
The consequences are unspecified if any argument other than the first is zero. If there is only one argument, the consequences are unspecified if it is zero.
Might signal type-error if some argument is not a number . Might signal division-by-zero if division by zero is attempted. Might signal arithmetic-error.
