Class

Function

Syntax

(= [expr ...])

Arguments and Values

  • one or more expressions acceptable to numeric/string comparison semantics

Description

Compares arguments for equality under AutoLISP comparison semantics.

Return Values

  • T if all arguments compare equal
  • nil otherwise

Side Effects

Side effects are those of evaluating the argument expressions.

Compatibility

Autodesk comparison functions accept strings as well as numbers in documented summaries, so this should not be reduced to a purely numeric predicate without tighter source confirmation.

Availability

  • AutoCAD 2026: documented (per Autodesk reference page).
  • BricsCAD V26: presumed compatible (no contradicting page found).
  • Status: AutoCAD documented; BricsCAD presumed-both pending Phase 4 verification.
