Basic Examples  (3)

Check numeric equality:

Wolfram Language code: EqualTo[2][2]

For symbolic expressions, the result is given as an equality:

Wolfram Language code: EqualTo[y][x]

Select the numbers that are equal to zero:

Wolfram Language code: Select[{-1, 0, 0., 10. ^ -100}, EqualTo[0]]

Scope  (4)

Use EqualTo with numbers:

Wolfram Language code: EqualTo[10][6]

Use EqualTo with numeric Quantity objects:

Wolfram Language code: EqualTo[Quantity[1, "Hour"]][Quantity[60, "Minutes"]]

Use EqualTo with dates:

Wolfram Language code: EqualTo[Today][Yesterday]

Use symbolic values:

Wolfram Language code: EqualTo[5][x]
Wolfram Language code: EqualTo[x][5]

Properties & Relations  (1)

For implicit entities with numeric properties, prop->val is equivalent to prop->EqualTo[val]:

Wolfram Language code: EntityValue[EntityClass["Particle", {"Bottomness" -> 1}], "Entities"]
Wolfram Language code: % === EntityValue[EntityClass["Particle", {"Bottomness" -> EqualTo[1]}], "Entities"]
