Hex-core-fconst-frac

Make-hex-core-fconst-frac

Basic constructor macro for hex-core-fconst-frac structures.

Syntax

(make-hex-core-fconst-frac [:significand <significand>] 
                           [:expo <expo>])

This is the usual way to construct hex-core-fconst-frac structures. It simply conses together a structure with the specified fields.

This macro generates a new hex-core-fconst-frac structure from scratch. See also change-hex-core-fconst-frac, which can "change" an existing structure, instead.

Definition

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

Macro: make-hex-core-fconst-frac

  (std::make-aggregate 'hex-core-fconst-frac
                       args '((:significand) (:expo))
                       'make-hex-core-fconst-frac
                       nil))

Function: hex-core-fconst-frac

(defun hex-core-fconst-frac (significand expo)
  (declare (xargs :guard (and (hex-frac-constp significand)
                              (bin-expop expo))))
  (declare (xargs :guard t))
  (b* ((significand (mbe :logic (hex-frac-const-fix significand)
                         :exec significand))
       (expo (mbe :logic (bin-expo-fix expo)
                  :exec expo)))
    (cons :frac (cons significand expo))))
