This class adds missing functions missing in BCMath.
It uses the BCMath extension functions to add more math operation functions that the extension is missing.
Currently it adds functions like floor, ceil, round, abs, min, max and rand.
|The BCMath extension can perform several types of operations with numbers of unlimited precision.
This class can implement several types of arbitrary precision operations not yet implemented by the BCMath extension like floor, ceil, round, abs, min, max and rand.
Extends php BCMath lib for missing functions like floor, ceil, round, abs, min, max, rand for big numbers.
Also wraps existing BCMath functions. (more http://php.net/manual/en/book.bc.php)
composer require krowinski/bcmath-extended
- setTrimTrailingZeroes - disable|enable trailing zeros (default trimming is enabled)
new tool methods
- convertScientificNotationToString - converts scientific notation to string
- getScale - gets current global scale
- getDecimalsLengthFromNumber - gets amount of decimals
- hexdec - converting from hexadecimal to decimal
- dechex - converting from decimal to hexadecimal
- bin2dec - converting from binary to decimal
- dec2bin - converting from decimal to binary
new math functions
- pow (supports fractional)
- mod (supports fractional + scale in php 5.6 <)
- bitwise operators
proxy for original functions (http://php.net/manual/en/book.bc.php)
all functions supports scientific notation
all functions are static, so it can be easy replaced by this lib
As of 7.2 float can be passed to bcmod but they don't return correct values (IMO)
I created bug for this in https://bugs.php.net/bug.php?id=76287 but it was commented as documentation issue not a bug.
bcmod() doesn't use floor() but rather truncates towards zero,
which is also defined this way for POSIX fmod(), so that the
result always has the same sign as the dividend. Therefore, this
is not a bug, but rather a documentation issue.
But I still will use floor not truncated for mod in this lib.
