Double-value

Make-double-value

Basic constructor macro for double-value structures.

Syntax

(make-double-value [:double <double>])

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

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

                       nil))

Function: double-value

    (declare (ignorable __function__))
    (b* ((double (mbe :logic (double-value-abs-fix double)
                      :exec double)))
