Const-float

Make-const-float

Basic constructor macro for const-float structures.

Syntax

(make-const-float [:fconst <fconst>])

This is the usual way to construct const-float structures. It simply conses together a structure with the specified fields.

This macro generates a new const-float structure from scratch. See also change-const-float, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-const-float

(defmacro make-const-float (&rest args)
  (std::make-aggregate 'const-float
                       args '((:fconst))
                       'make-const-float
                       nil))

Function: const-float

(defun const-float (fconst)
  (declare (xargs :guard (fconstp fconst)))
  (declare (xargs :guard t))
  (b* ((fconst (mbe :logic (fconst-fix fconst)
                    :exec fconst)))
    (cons :float fconst)))
