Page Summary
-
The
Array.eqmethod performs element-wise equality comparison between two arrays. -
It returns 1 if the corresponding elements are equal and 0 otherwise.
-
The method handles different data types and floating-point comparisons, which can sometimes result in 0 even when values appear equal at first glance due to internal representation.
-
The method can be used with both JavaScript and Python implementations.

var empty = ee . Array ([], ee . PixelType . int8 ()); print ( empty . eq ( empty )); // [] print ( ee . Array ([ 0 ]). eq ( ee . Array ([ 1 ]))); // 0 print ( ee . Array ([ 0 ]). eq ( ee . Array ([ 0 ]))); // 1 print ( ee . Array ([ 1.1 ]). eq ( ee . Array ([ 1.1 ]))); // 1 print ( ee . Array ([ 1.1 ]). float (). eq ( ee . Array ([ 1.1 ]))); // 0 print ( ee . Array ([ 1.1 ]). double (). eq ( ee . Array ([ 1.1 ]))); // 1 print ( ee . Array ([ 1 ]). int8 (). eq ( ee . Array ([ 1 ]))); // 1 print ( ee . Array ([ 1 ]). int8 (). eq ( ee .
