Aggregation Expression - $log10

Function Build

Build $log10 with the Log10 function from the aggregation package.

// bson.D{bson.E{Key:"result", Value:bson.D{bson.E{Key:"$log10", Value:"$value"}}}}
result := aggregation.Log10("result", "$value")

Method Build (Builder)

Build $log10 with the Log10 method from aggregation.NewBuilder().

// bson.D{bson.E{Key:"result", Value:bson.D{bson.E{Key:"$log10", Value:"$value"}}}}
result := aggregation.NewBuilder().
    Log10("result", "$value").
    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.

Log10WithoutKey

This variant is currently available as a builder method.

Method build (Builder):

// bson.D{bson.E{Key:"$log10", Value:"$value"}}
expr := aggregation.NewBuilder().
    Log10WithoutKey("$value").
    Build()
