setPrecision(int $precision)
Sets the precision for inaccurate fraction conversions.
The fractions cannot always be accurately converted from base to another, since they may represent a fraction that cannot be represented in another number base. The precision value is used to determine the number of digits in the fractional part, if the number cannot be accurately converted or if it is not feasible to determine that.
If the precision is positive, it defines the maximum number of digits in the fractional part. If the value is 0, the converted number will have at least as many digits in the fractional part as it takes to represent the number in the same accuracy as the original number. A negative number will simply increase the number of digits.
Note that the fractional part may have fewer digits than what is required by the precision if it can be accurately represented using fewer digits.

array
convertInteger(array $number)
Converts the integer part of a number.
The integer part should be provided as an array of digits with least significant digit first. Any invalid digit in the array will cause an exception to be thrown. The return value will be a similar array of digits, except converted to the target number base.
