Aggregation Expression - $mod

Function Build

Build $mod with the Mod function from the aggregation package.

// bson.D{bson.E{Key:"remainder", Value:bson.D{bson.E{Key:"$mod", Value:[]interface {}{"$age", 5}}}}}
result := aggregation.Mod("remainder", "$age", 5)

Method Build (Builder)

Build $mod with the Mod method from aggregation.NewBuilder().

// bson.D{bson.E{Key:"remainder", Value:bson.D{bson.E{Key:"$mod", Value:[]interface {}{"$age", 5}}}}}
result := aggregation.NewBuilder().
    Mod("remainder", "$age", 5).
    Build()

Build Without Key

When an expression needs to be passed as an argument to another expression, use a WithoutKey variant to build an expression fragment without an output field name.

ModWithoutKey

Function build:

// bson.D{bson.E{Key:"$mod", Value:[]any{"$age", 5}}}
expr := aggregation.ModWithoutKey("$age", 5)

Method build (Builder):

// bson.D{bson.E{Key:"$mod", Value:[]any{"$age", 5}}}
expr := aggregation.NewBuilder().
    ModWithoutKey("$age", 5).
