Integer Parser

Package integer provides utilities to convert arbitrary values into int values.

Unlike float or decimal, this parser always truncates toward zero.
No fractional values are preserved.

Features

• Supports:
• Signed and unsigned integers
• Floats (fractional part truncated)
• Strings (parsed as float then truncated)
• Bools (true → 1, false → 0)
• Pointers and interfaces wrapping supported types
• Rejects unsupported types with clear errors
• Safe: never panics

Installation

import "github.com/entiqon/common/extension/integer"

Usage

package main

import (
    "fmt"

    "github.com/entiqon/common/extension/integer"
)

func main() {
    v1, _ := integer.ParseFrom(42)
    fmt.Println(v1) // 42

    v2, _ := integer.ParseFrom(3.99)
    fmt.Println(v2) // 3

    v3, _ := integer.ParseFrom("123")
    fmt.Println(v3) // 123

    v4, _ := integer.ParseFrom(true)
    fmt.Println(v4) // 1
}

Notes

• Truncation: 3.99 → 3, -1.9 → -1, 0.5 → 0.
• Returns (0, error) if input is nil, empty string, or unsupported type.
