Float Parser 🌊

Utilities to parse various types into float64.

Part of the entiqon common/extension toolkit.

✨ Features

  • Convert values (string, int, float, bool) into float64
  • Support for pointers and interface wrappers
  • No rounding — values are preserved as-is
  • Safe error handling for unsupported/invalid inputs
  • Full test coverage (file → methods → cases)

📑 API Reference

ParseFrom(value any) (float64, error)

Convert supported inputs into float64.

Supported inputs:

  • int / int8 / int16 / int32 / int64
  • uint / uint8 / uint16 / uint32 / uint64 / uintptr
  • float32 / float64
  • string → parsed as float
  • bool → true → 1.0, false → 0.0
  • pointers/interfaces wrapping the above

Unsupported:

  • nil
  • unsupported structs, slices, maps, complex, etc.

🔹 Usage Examples

package main

import (
    "fmt"
    "github.com/entiqon/common/extension/float"
)

func main() {
    f1, _ := float.ParseFrom("123.456")
    fmt.Println(f1)

    f2, _ := float.ParseFrom(42)
    fmt.Println(f2)

    f3, _ := float.ParseFrom(true)
    fmt.Println(f3)
}

Output:

123.456
42
1

📌 Summary

  • Core: ParseFrom(any) (float64, error)
  • No rounding: values preserved
  • Safe: clear errors on invalid/unsupported inputs
