This library makes use of the GMP extension and bcmath to do its calculations. Introduction ------------ [](#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 ------- [](#install) Via Composer ``` $ composer require bardoqi/bigmath:dev-master ``` Usage ----- [](#usage) ``` //with pecl Operator overloading extension: $number = BInt('8273467836243255543265432745') + BInt('2'); //without pecl Operator overloading extension: $number = BInt('8273467836243255543265432745')->add(BInt('2')); ``` Features -------- [](#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: ``` //to get a new BigInteger instance of $var; BInt($var); //to get a new BigDecimal instance of $var; BDec($var); ``` - Simple init Mothod: of(string $value) - Support using with [pecl Operator overloading extension](https://github.com/php/pecl-php-operator), there are operators could be used: OperatorMethod$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](https://github.com/php/pecl-php-operator), there are mothods of operators could be used: Operatorsmethod+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: ``` //with pecl Operator overloading extension: $x=($a+$b)*($c-$d); //without pecl Operator overloading extension: $x=BInt($a)->add(BInt($b))->multiply(BInt($c)->substract(BInt($d))); ``` Sample Code ----------- [](#sample-code) ``` //with Operator overloading extension: //if sample: if(abs($big_g)>abs($big_m)){ $big_g = $big_g % $big_m; } //while sample: While (rt_v!=1){ $x = $rd_v/$rt_v; //... } //for sample: for($i=$xstart; $iabs($big_m)){...} if ($big_g->abs()->gt($big_m->abs())){ $big_g = $big_g->mod($big_m); } //while sample: //While (rt_v!=1){...} while (!($rt_v->isOne())){ //rt!=1 //x=rd/rt $x = $rd_v->div($rt_v); //... } //for sample: //for($i=$xstart; $ilt(BInt($xMax)); $i->plus($step)){ $item = &$data[]; $item['x']=$i; } //More samples please read the code in exanples! ``` Change log ---------- [](#change-log) Please see [CHANGELOG](CHANGELOG.md) for more information what has changed recently.
