FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package bigmath
BigMath
A PHP library to work with big integers. This library makes use of the GMP extension and bcmath to do its calculations.
Introduction
Maybe you ara a developer of blockchain using php. Maybe you often coding encrypt and decrypt. And you fund that there is no library easy to use for big integer or high precision number in php. Now you could coding in most easy way with the BigMath!
Install
Via Composer
Usage
Features
This library supports the following operations:
-
Big Intgeger and high precision decimal support ....Class BigInteger: using with GMP. ....Class BigDecminal: using with bcmath.
-
Global type converting functions; .... You need not use 'new' operator to create new object. .... You Only need use:
-
Simple init Mothod: of(string $value)
- Support using with pecl Operator overloading extension, there are operators could be used:
| Operator | Method |
|---|---|
| $o + $arg | __add($arg) |
| $o - $arg | __sub($arg) |
| $o * $arg | __mul($arg) |
| $o / $arg | __div($arg) |
| $o % $arg | __mod($arg) |
| $o ** $arg | __pow($arg) |
| $o . $arg | __concat($arg) |
| $o | $arg | __bw_or($arg) |
| $o & $arg | __bw_and($arg) |
| $o ^ $arg | __bw_xor($arg) |
| $o === $arg | __is_identical($arg) |
| $o !== $arg | __is_not_identical($arg) |
| $o == $arg | __is_equal($arg) |
| $o != $arg | __is_not_equal($arg) |
| $o < $arg | __is_smaller($arg) |
| $o <= $arg | __is_smaller_or_equal($arg) |
| $o > $arg | __is_greater($arg) * |
| $o >= $arg | __is_greater_or_equal($arg) * |
| $o <=> $arg | __cmp($arg) |
| ++$o | __pre_inc() |
| $o++ | __post_inc() |
| --$o | __pre_dec() |
| $o-- | __post_dec() |
| $o = $arg | __assign($arg) |
| $o += $arg | __assign_add($arg) |
| $o -= $arg | __assign_sub($arg) |
| $o *= $arg | __assign_mul($arg) |
| $o /= $arg | __assign_div($arg) |
| $o %= $arg | __assign_mod($arg) |
| $o **= $arg | __assign_pow($arg) |
| $o |= $arg | __assign_bw_or($arg) |
| $o &= $arg | __assign_bw_and($arg) |
| $o ^= $arg | __assign_bw_xor($arg) |
- If without pecl Operator overloading extension, there are mothods of operators could be used:
| Operators | method |
|---|---|
| + | add() |
| - | sub(), substract() |
| * | mul(), multiply() |
| / | div(), divide() |
| % | mod() |
| ** | pow(), power() |
| ++ | plus(), increment() |
| -- | minus(), devrement |
| == | eq(), equals() |
| != | ne(), notEquals() |
| === | identical() |
| !== | notIdentical(() |
| > | gt(), greaterThan() |
| >= | gte() greaterThanOrEqualsTo() |
| < | lt(), lessThan() |
| <= | lte(), lessThanOrEqualsTo() |
| <=> | cmp(), compareTo() |
| - | negate() |
| . | concat() |
- Mothods for coding simple: max(); min(); even(); odd(); sign(); isOne(); isZero(); randomRange();
- Mothods of Mathematics:
abs(); divideRem; powMod(); squareRoot();
factorial(); gcd(); - Mothods for bit orpeator(Only in BigInteger) andBits(); orBits(); clearBits(); complement() invert(); setBit(); testBit(); scan0(); scan1();
- Mothods of Math Theory(Only in BigInteger) isPrime(); jacobi(); legendre(); perfectSquare() popcount(); root();
- Chain Operators support: You can just use:
