Methods Summary
`public static`	# `of( \BigNumber\|\number\|string $value )` 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 returned as BigDecimal - strings containing a `/` character are returned as BigRational - strings containing a `.` character or using an exponentional notation are returned as BigDecimal - strings containing only digits with an optional leading `+` or `-` sign are returned as BigInteger
`public static`	# `min( \BigNumber\|\number\|string $values ,… )` Returns the minimum of the given values.
`public static`	# `max( \BigNumber\|\number\|string $values ,… )` Returns the maximum of the given values.
`public`	# `isEqualTo( \BigNumber\|\number\|string $that )` Checks if this number is equal to the given one.
`public`	# `isLessThan( \BigNumber\|\number\|string $that )` Checks if this number is strictly lower than the given one.
`public`	# `isLessThanOrEqualTo( \BigNumber\|\number\|string $that )` Checks if this number is lower than or equal to the given one.
`public`	# `isGreaterThan( \BigNumber\|\number\|string $that )` Checks if this number is strictly greater than the given one.
`public`	# `isGreaterThanOrEqualTo( \BigNumber\|\number\|string $that )` Checks if this number is greater than or equal to the given one.
`public`	# `isZero( )` Checks if this number equals zero.
`public`	# `isNegative( )` Checks if this number is strictly negative.
`public`	# `isNegativeOrZero( )` Checks if this number is negative or zero.
`public`	# `isPositive( )` Checks if this number is strictly positive.
`public`	# `isPositiveOrZero( )` Checks if this number is positive or zero.
`abstract public`	# `getSign( )` Returns the sign of this number.
`abstract public`	# `compareTo( \BigNumber\|\number\|string $that )` Compares this number to the given one.
`abstract public`	# `toBigInteger( )` Converts this number to a BigInteger.
`abstract public`	# `toBigDecimal( )` Converts this number to a BigDecimal.
`abstract public`	# `toBigRational( )` Converts this number to a BigRational.
`abstract public`	# `toScale( int $scale , int $roundingMode = 0 )` Converts this number to a BigDecimal with the given scale, using rounding if necessary.
`abstract public`	# `toInt( )` Returns the exact value of this number as a native integer. If this number cannot be converted to a native integer without losing precision, an exception is thrown. Note that the acceptable range for an integer depends on the platform and differs for 32-bit and 64-bit.
`abstract public`	# `toFloat( )` Returns an approximation of this number as a floating-point value. Note that this method can discard information as the precision of a floating-point value is inherently limited.
`abstract public`	# `__toString( )` Returns a string representation of this number. The output of this method can be parsed by the `of()` factory method; this will yield an object equal to this one, without any information loss.
`public`	# `jsonSerialize( )` {@inheritdoc} Implementation of `JsonSerializable::jsonSerialize()`
