Cannot decode integers into floats

[horgh]

Describe the bug
I have a config with entries like

foo = 5

And I would like to decode them into a float64. This errors with: toml: cannot decode TOML integer into struct field main.conf.Foo of type float64

To Reproduce

package main

import (
        "log"

        toml "github.com/pelletier/go-toml/v2"
)

func main() {
        type conf struct {
                Foo float64 `json:"foo"`
        }
        var c conf

        buf := []byte(`foo = 5`)

        if err := toml.Unmarshal(buf, &c); err != nil {
                log.Fatal(err)
        }
        log.Printf("%+v", c)
}

Expected behavior
I think it would be good to be able to deserialize ints into floats. encoding/json works that way for instance.

Versions

• go-toml: github.com/pelletier/go-toml/v2 v2.0.6
• go: go version go1.19.4 linux/amd64
• operating system: Linux

Additional context
I could write the config values as 5.0 to get around this. However the same config is also used by a Perl parser, which has a different issue when expressing numbers as 5.0. It would be helpful in my case to be able to leave it as "5".

Thank you!
