(=?) : 'a -> 'a -> bool

SYNOPSIS

Reflexive short-cutting equality test.

DESCRIPTION

This is functionally identical to the OCaml equality test = except that it is reflexive even on floating-point NaN. More importantly, it will more efficiently short-cut comparisons of large data structures where subcomponents are identical (pointer equivalent).

FAILURE CONDITIONS

May fail when applied to functions.

EXAMPLE

  # let x = 0.0 /. 0.0;;
  val x : float = nan
  # x = x;;
  val it : bool = false
  # x =? x;;
  val it : bool = true
