Aggregation Expression - $divide

Function Build

Build $divide with the Divide function from the aggregation package.

// bson.D{bson.E{Key:"avgPrice", Value:bson.D{bson.E{Key:"$divide", Value:[]interface {}{"$total", "$count"}}}}}
result := aggregation.Divide("avgPrice", "$total", "$count")

Method Build (Builder)

Build $divide with the Divide method from aggregation.NewBuilder().

// bson.D{bson.E{Key:"avgPrice", Value:bson.D{bson.E{Key:"$divide", Value:[]interface {}{"$total", "$count"}}}}}
result := aggregation.NewBuilder().
    Divide("avgPrice", "$total", "$count").
    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.

DivideWithoutKey

Function build:

// bson.D{bson.E{Key:"$divide", Value:[]any{"$total", "$count"}}}
expr := aggregation.DivideWithoutKey("$total", "$count")

Method build (Builder):

// bson.D{bson.E{Key:"$divide", Value:[]any{"$total", "$count"}}}
expr := aggregation.NewBuilder().
    DivideWithoutKey("$total", "$count").
    Build()
