🎉 IntPrecisionHelper v1.1.0 - Universal Type Conversion

Major new features with zero breaking changes!

🚀 New Universal Methods

normalize(mixed $value): int

Auto-detects input type and converts to normalized integer:

IntPrecisionHelper::normalize(12.34);    // 1234 (float)
IntPrecisionHelper::normalize("12.34");  // 1234 (string)  
IntPrecisionHelper::normalize(12);       // 1200 (integer)

denormalize(int $value): float

Clean conversion back to decimal float:

IntPrecisionHelper::denormalize(1234);  // 12.34

✨ Key Benefits

  • 🔍 Auto-detection - No need to know input type beforehand
  • 🎯 Perfect round-trips - Exact precision preservation
  • 🛡️ Type safety - Comprehensive validation with clear error messages
  • ⚡ Performance options - Support for less precise mode
  • 📚 Zero breaking changes - All existing code works unchanged

📊 Enhanced Testing

  • 74 unit tests (+10 new)
  • 556 feature scenarios (+45 new)
  • 100% code coverage maintained

🔧 Quick Start

// Universal approach (recommended for new code)
$normalized = IntPrecisionHelper::normalize($anyValue);
$result = IntPrecisionHelper::denormalize($normalized);

// Existing methods still work exactly the same
$normalized = IntPrecisionHelper::fromString("12.34");
$result = IntPrecisionHelper::toFloat($normalized);

📥 Installation

composer require gryfoss/int-precision-helper:^1.1
# or upgrade: composer update gryfoss/int-precision-helper

Making decimal precision handling even easier while maintaining perfect backward compatibility! 🎯

IntPrecisionHelper v1.0.0 Release Notes

🎉 First Stable Release - October 11, 2025

We're excited to announce the first stable release of IntPrecisionHelper - a robust PHP library for handling decimal precision by storing floating-point numbers as integers, designed to eliminate floating-point precision issues in database storage and financial calculations.

🌟 What's New in v1.0.0

✨ Core Features

Precision Conversion Methods

  • fromString(string $value, bool $lessPrecise = false): int - Convert string decimals to normalized integers
  • fromFloat(float $value, bool $lessPrecise = false): int - Convert floats to normalized integers
  • toView(int $value, int $decimalPlaces = 2): string - Convert back to human-readable format
  • toFloat(int $value): float - Convert back to float representation

Mathematical Operations

  • normMul(int ...$numbers): int - Multiply normalized integers with precision preservation
  • normDiv(int $dividend, int $divisor): int - Divide normalized integers safely
  • normAdd(int ...$values): int - Add multiple normalized integers
  • normSub(int $minuend, int $subtrahend): int - Subtract normalized integers

Utility Methods

  • calculatePercentage(int $count, int $totalCount): ?int - Calculate percentages as normalized integers
  • normCompare(int $a, int $b): int - Compare normalized integers (-1, 0, 1)
  • isValid(mixed $value): bool - Validate normalized integer values

🛡️ Robust Error Handling

Input Validation

// Throws InvalidArgumentException for invalid inputs
IntPrecisionHelper::fromString("invalid");
IntPrecisionHelper::fromString("1.23e5"); // Scientific notation not supported

Division Protection

// Throws DivisionByZeroError
IntPrecisionHelper::normDiv(1234, 0);
IntPrecisionHelper::calculatePercentage(50, 0); // Returns null safely

Overflow Protection

// Throws OverflowException for results exceeding PHP_INT_MAX
IntPrecisionHelper::normMul(PHP_INT_MAX, PHP_INT_MAX);

⚡ Performance & Precision

PHP 8.4+ Native bcround()

  • Utilizes PHP 8.4's native bcround() function for optimal performance
  • High-precision decimal operations using BCMath extension
  • Configurable precision modes for performance-critical applications

Smart Precision Handling

// Standard precision (recommended)
$result = IntPrecisionHelper::fromString("12.34");

// Performance mode for very large numbers
$result = IntPrecisionHelper::fromString("12.34", true);

🎯 Real-World Usage Examples

Financial Calculations

// Store monetary values as integers (avoiding floating-point errors)
$price = IntPrecisionHelper::fromString("19.99");        // 1999
$tax = IntPrecisionHelper::calculatePercentage(825, 100); // 825 (8.25%)
$total = IntPrecisionHelper::normAdd($price, $tax);       // 2824
$display = IntPrecisionHelper::toView($total);            // "28.24"

E-commerce Discounts

$originalPrice = IntPrecisionHelper::fromString("99.99");  // 9999
$discount = IntPrecisionHelper::calculatePercentage(20, 100); // 2000 (20%)
$discountAmount = IntPrecisionHelper::normMul($originalPrice, $discount);
$finalPrice = IntPrecisionHelper::normSub($originalPrice, $discountAmount);
echo IntPrecisionHelper::toView($finalPrice); // "79.99"

Database Storage

// Store in database as integer
$userBalance = IntPrecisionHelper::fromString($userInput);
$db->query("INSERT INTO accounts (balance) VALUES (?)", [$userBalance]);

// Retrieve and display
$balanceInt = $db->fetchColumn("SELECT balance FROM accounts WHERE id = ?", [$userId]);
$balanceDisplay = IntPrecisionHelper::toView($balanceInt);
