long-float-epsilon
Constant
The value of this constant is the smallest positive floating-point number e
of a format such that it satisfies the expression:
(not (= (float 1 e) (+ (float 1 e) e»)
In Symbolics Common Lisp long-float-epsilon has the same value as
double-float-epsilon, namely: 1.1102230246251568d-16.
long-float-negative-epsilon
Constant
The value of this constant is the smallest positive floating-point number e
of a format such that it satisfies the expression:
(not (= (float 1 e) (- (float 1 e) e»)
In Symbolics Common Lisp the value of long-float-negative-epsilon is the
same as that of double-float-negative-epsilon, namely:
5.551115123125784d-17.
loop &rest forms Macro
loop is a Lisp macro that provides a programmable iteration facility. The
Symbolics Common Lisp implementation of loop is an extension of the
Common Lisp specification for this macro in Guy L. Steele's Common Lisp:
the Language. loop works identically in Symbolics Common Lisp and in
Zetalisp.
The general approach is that a form introduced by the word loop generates
a single program loop, into which a large variety of features can be incorporated.
The loop consists of some initialization (prologue) code, a body
that can be executed several times, and some exit (epilogue) code. Variables
can be declared local to the loop. The features are concerned with
loop variables, deciding when to end the iteration, putting user-written code
into the loop, returning a value from the construct, and iterating a variable
through various real or virtual sets of values.
