# Builtins.identical(3kaya)

Return whether two values are identical.

## NAME

Builtins::identical - Return whether two values are identical.

## SYNOPSIS

**Bool identical(** *a x, a y* **)**

## ARGUMENTS

**x** First value

**y** Second value

## DESCRIPTION

Check if two values are identical. This is stronger than equality - this tests whether two values are stored at the same memory location. In other words, it tests whether modifying the contents of *x* would also modify the contents of *y*

-

   a = (5,6);\
    b = (3,a.snd);                        \
    c = a;\
    d = (5,6);\
    test = identical(b,a); // false                       \
    test2 = identical(b.snd,a.snd); //true\
    test3 = identical(c,a); // true\
    test4 = identical(d,a); // false

Of course, **equal(a,d)**  would be **true**
