# tez-utils-num
PHP number utilities: formatting, byte sizes, percentage, clamping, and rounding helpers (`Num`), plus arbitrary-precision decimal arithmetic via bcmath (`Bc`). PHP 8.3+, requires `ext-bcmath`.
## Installation
```bash
composer require tez/utils-num
```
## Components
| Class | Purpose |
|-------|---------|
| `Num` | Formatting, byte sizes, percentages, clamping, rounding |
| `Bc` | Arbitrary-precision decimal arithmetic wrapping `ext-bcmath` |
---
## Num
Formatting and rounding helpers for everyday number display.
### format()
```php
use Tez\Utils\Num\Num;
Num::format(1234567.891); // '1,234,567.89'
Num::format(1234567.891, dec: ',', thousands: '.'); // '1.234.567,89'
Num::format(1234.5, decimals: 0); // '1,235'
Num::format(-1000.0); // '-1,000.00'
```
### bytes()
Converts a byte count to a human-readable string using binary units (1 KB = 1 024 B).
```php
Num::bytes(0); // '0 B'
Num::bytes(1023); // '1,023 B'
Num::bytes(1024); // '1.00 KB'
Num::bytes(1048576); // '1.00 MB'
Num::bytes(1073741824); // '1.00 GB'
Num::bytes(1024 ** 4); // '1.00 TB'
Num::bytes(1500, precision: 0); // '1 KB'
```
### percent()
Formats a ratio (`0.0``1.0`) as a percentage string.
```php
Num::percent(0.1234); // '12.3%'
Num::percent(1.0); // '100.0%'
Num::percent(0.0056, decimals: 2); // '0.56%'
```
### clamp()
Constrains a value to the inclusive range `[$min, $max]`.
```php
Num::clamp(105, 0, 100); // 100
Num::clamp(-5, 0, 100); // 0
Num::clamp(50, 0, 100); // 50
Num::clamp(1.5, 0.0, 0.5); // 0.5
```
### roundTo()
Rounds a value to the nearest multiple of `$multiple`.
```php
Num::roundTo(17, 5); // 15
Num::roundTo(18, 5); // 20
Num::roundTo(1.7, 0.5); // 1.5
```
---
## Bc
Arbitrary-precision decimal arithmetic wrapping PHP's `bcmath` extension. Designed for financial calculations where floating-point imprecision is not acceptable.
**All inputs must be numeric strings** (e.g. `'1.50000000'`). Passing a non-numeric string throws `\InvalidArgumentException`. Division by zero throws `\DivisionByZeroError`.
The default scale is **8 decimal places** for all methods.
### Arithmetic
```php
use Tez\Utils\Num\Bc;
Bc::add('10.5', '20.3'); // '30.80000000'
Bc::sub('20.3', '11.1'); // '9.20000000'
Bc::mul('4', '5'); // '20.00000000'
Bc::div('1', '3'); // '0.33333333'
Bc::div('1', '3', scale: 2); // '0.33'
// Array operations
Bc::sum(['1', '2', '3']); // '6.00000000'
Bc::sum([]); // '0.00000000'
Bc::product(['2', '3', '4']); // '24.00000000'
Bc::product([]); // '1.00000000'
Bc::subAll(['10', '3', '2']); // '5.00000000' (10 - 3 - 2)
Bc::divAll(['100', '5', '4']); // '5.00000000' (100 / 5 / 4)
```
### Utilities
```php
Bc::abs('-5'); // '5.00000000'
Bc::negate('3.14'); // '-3.14000000'
Bc::negate('-5'); // '5.00000000'
Bc::max('10', '5'); // '10.00000000'
Bc::min('10', '3'); // '3.00000000'
Bc::scale('1.5'); // '1.50000000' — normalize to 8 decimal places
Bc::scale('1.123456789'); // '1.12345678' — truncates, does not round
Bc::percent('200', '15'); // '30.00000000' — 15% of 200
```
### Comparisons
```php
Bc::compare('10', '5'); // 1 (greater)
Bc::compare('5', '10'); // -1 (less)
Bc::compare('5.00', '5'); // 0 (equal)
Bc::eq('5.00', '5.000'); // true
Bc::gt('10', '5'); // true
Bc::lt('3', '7'); // true
Bc::gte('5', '5'); // true
Bc::lte('3', '7'); // true
Bc::isZero('0.00000000'); // true
Bc::isZero('0.00000001'); // false
Bc::isPositive('0.00000001'); // true
Bc::isNegative('-0.00000001'); // true
```
### Scale behaviour
`Bc::scale()` truncates (does not round). All arithmetic methods default to scale 8 and accept an explicit `scale` parameter:
```php
Bc::add('10.5', '20.3', scale: 2); // '30.80'
Bc::div('1', '3', scale: 4); // '0.3333'
// Equal at scale 2, different at scale 8
Bc::eq('5.001', '5.009', scale: 2); // true
Bc::eq('5.001', '5.009'); // false
```
