math
(even? x)
Defined at lib/math/init.lisp:27:2
Is X an even number?
Example
> (even? 2)
out = true
> (even? 1)
out = false
(gcd x y)
Defined at lib/math/init.lisp:3:2
Compute the greatest common divisor of X and Y.
Example
> (gcd 52 32)
out = 4
(lcm x y)
Defined at lib/math/init.lisp:16:2
Compute the lowest common multiple of X and Y.
Example
> (lcm 52 32)
out = 416
(nan? x)
Defined at lib/math/init.lisp:51:2
Is X equal to NaN?
Example
> (nan? (/ 0 0))
out = true
> (nan? 1)
out = false
(odd? x)
Defined at lib/math/init.lisp:39:2
Is X an odd number?
Example
> (odd? 1)
out = true
> (odd? 2)
out = false
(pred x)
Defined at lib/math/init.lisp:67:2
Return the predecessor of the number X.
(round x)
Defined at lib/math/init.lisp:73:2
Round X, to the nearest integer.
Example:
> (round 1.5)
out = 2
> (round 1.3)
out = 1
> (round -1.3)
out = -1
(succ x)
Defined at lib/math/init.lisp:63:2
Return the successor of the number X.
