zl:1 - FTP

zl:1 4
I
I follows normal mathematical rules, so if the mathematical quotient of two
integers is not an exact integer, the function returns a ratio. To obtain an
integer result, use one of these functions: floor, ceiling, truncate, round.
(I 4) => 1/4
(I 4.9) => 9.25
(I 9 3) => 3
(I 18 4) => 9/2 jreturns rational number in canonical form
(I 191 19.9) => 19.1 japplies coercion rules
(I 191 19) => 191/19
(I 24 4 2) => 3
(I 36. 4. 3.) => 3
(I 36.9 4.9 3.9) => 3.9
(I #c(1 1) #c(1 -1» => #c(9 1)
(I #c(3 4) 5) => #c(3/5 4/5)

zl:1 number &rest more-numbers Function
With more than one argument, zl:1 is the same as zl:quotient; it returns
the irrst argument divided by all of the rest of its arguments. With only
one argument, (zl:1 x) is the same as (zl:1 1 x).
With integer arguments, zl:1 acts like truncate, except that it returns only
a single value, the quotient.
Note that in Zetalisp syntax I is the quoting character and must therefore
be doubled.
Examples:
(zl!1 3 2) => 1 ;Integer division truncates.
(zl:/3 -2) => -1
(zl:1 -3 2) => -1
(zl:1 -3 -2) => 1
(zl:/3 2.9) => 1.5
(zl:/3 2.9d9) => 1.5d9
(zl:/4 2) => 2
(zl:1 12. 2. 3.) => 2
(zl:1 4.9) => .25
The following function is a synonym of zl:1 :
