**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**.**See Also**
