| of($value) X-Ref |
| Creates a BigNumber of the given value. The concrete return type is dependent on the given value, with the following rules: - BigNumber instances are returned as is - integer numbers are returned as BigInteger - floating point numbers are converted to a string then parsed as such - strings containing a `/` character are returned as BigRational - strings containing a `.` character or using an exponential notation are returned as BigDecimal - strings containing only digits with an optional leading `+` or `-` sign are returned as BigInteger param: BigNumber|int|float|string $value return: BigNumber |
| floatToString(float $float) X-Ref |
| Safely converts float to string, avoiding locale-dependent issues. param: float $float return: string |
| create(... $args) X-Ref |
| Proxy method to access protected constructors from sibling classes. param: mixed ...$args The arguments to the constructor. return: static |
| min(...$values) X-Ref |
| Returns the minimum of the given values. param: BigNumber|int|float|string ...$values The numbers to compare. All the numbers need to be convertible return: static The minimum value. |
| max(...$values) X-Ref |
| Returns the maximum of the given values. param: BigNumber|int|float|string ...$values The numbers to compare. All the numbers need to be convertible return: static The maximum value. |
| sum(...$values) X-Ref |
| Returns the sum of the given values. param: BigNumber|int|float|string ...$values The numbers to add. All the numbers need to be convertible return: static The sum. |
| add(BigNumber $a, BigNumber $b) X-Ref |
| Adds two BigNumber instances in the correct order to avoid a RoundingNecessaryException. param: BigNumber $a param: BigNumber $b return: BigNumber |
| cleanUp(string $number) X-Ref |
| Removes optional leading zeros and + sign from the given number. param: string $number The number, validated as a non-empty string of digits with optional sign. return: string |
| isEqualTo($that) X-Ref |
| Checks if this number is equal to the given one. param: BigNumber|int|float|string $that return: bool |
| isLessThan($that) X-Ref |
| Checks if this number is strictly lower than the given one. param: BigNumber|int|float|string $that return: bool |

| Checks if this number is lower than or equal to the given one. param: BigNumber|int|float|string $that return: bool |
| isGreaterThan($that) X-Ref |
| Checks if this number is strictly greater than the given one. param: BigNumber|int|float|string $that return: bool |
| isGreaterThanOrEqualTo($that) X-Ref |
| Checks if this number is greater than or equal to the given one. param: BigNumber|int|float|string $that return: bool |
| isZero() X-Ref |
| Checks if this number equals zero. return: bool |
| isNegative() X-Ref |
| Checks if this number is strictly negative. return: bool |
| isNegativeOrZero() X-Ref |
| Checks if this number is negative or zero. return: bool |
| isPositive() X-Ref |
