====== eq ======
eq

===== Description =====
Two items are popped from the stack and compared for equality. 0 or 1 is pushed back to the stack where 1 indicates equal and 0 (zero) indicates not equal. \\
The equal/not equal evaluation can also be performed with “true” (1) and false(0), respectively. \\

  * If either item being compared is a float, a float comparison is performed.\\
  * If both items being compared are strings, a string comparison is performed.\\
  * If both items being compared are vectors, a vector comparison is performed.\\
  * If one item is a float and one item is a vector, the float is compared to the vector length.\\
  * If none of the above conditions are true, an integer comparison is performed.

Note: See [[4rpl:Data Types]] for comparison between dissimilar types and type conversion. 

===== Examples =====
<code 4rpl>
if (1 eq (1))
    trace("1 is equal to 1")
endif

#  alternate example

1 dup eq
if true
  trace ("one is always one")
endif
