Float64 Function Return

Float64 function return expects a 64-bit floating point number value from function logic. Set values in function logic with the Go built-in float64 type, Go built-in *float64 type, or the framework float64 type.

Function Definition

Use the function.Float64Return type in the function definition.

In this example, a function definition includes a float64 return:

func (f ExampleFunction) Definition(ctx context.Context, req function.DefinitionRequest, resp *function.DefinitionResponse) {
    resp.Definition = function.Definition{
        // ... other Definition fields ...
        Return: function.Float64Return{
            // ... potentially other Float64Return fields ...
        },
    }
}

Custom Types

You may want to build your own data value and type implementations to allow your provider to combine validation and other behaviors into a reusable bundle. This helps avoid duplication and ensures consistency. These implementations use the CustomType field in the return type.

Refer to Custom Types for further details on creating provider-defined types and values.

Documentation

Return documentation is expected in the top-level function documentation. Refer to function documentation for information about the Summary, Description, and MarkdownDescription fields available.

Setting Return Data

The function implementation documentation covers the general methods for setting function return data in function logic.

When setting the value for this return:

• If CustomType is set, use its associated value type.
• Otherwise, use the Go built-in float64 type, Go built-in *float64 type, or framework float64 type.

In this example, a function defines a float64 return and sets its value:

func (f ExampleFunction) Definition(ctx context.Context, req function.DefinitionRequest, resp *function.DefinitionResponse) {
    resp.Definition = function.Definition{
        // ... other Definition fields ...
        Return: function.Float64Return{},
    }
}

func (f ExampleFunction) Run(ctx context.Context, req function.RunRequest, resp *function.RunResponse) {
    // ... other logic ...

    // hardcoded value for example brevity
    result := 1.23

    resp.Error = function.ConcatFuncErrors(resp.Error, resp.Result.Set(ctx, &result))
}
