db16e619c3 Add BigDecimal::quotient() and remainder() methods 2015-07-03 18:05:02 +02:00
Benjamin Morel
271b619453 Rename BigDecimal::dividedAndRemainder() to quotientAndRemainder() 
This is consistent with the naming of the BigInteger method.

38a6b8c342 Add BigNumber::toInteger() and toFloat() methods 
These methods are implemented by BigInteger, BigDecimal and BigRational.

- toInteger() returns an exact value or throws an exception
- toFloat() returns an approximate value

45e3c3a463 Remove get prefix in method names 
This improves overall consistency of method names in the project.
For example, it does not make sense to get the reciprocal of a BigRational using reciprocal(), but get its numerator using getNumerator().

List of renamed methods:

- BigNumber::getSign() => sign()
- BigDecimal::getUnscaledValue() => unscaledValue()
- BigDecimal::getScale() => scale()
- BigDecimal::getIntegral() => integral()
- BigDecimal::getFraction() => fraction()
- BigRational::getNumerator() => numerator()
- BigRational::getDenominator() => denominator()

97c7c45c51 All BigNumber subclasses now have zero(), one() and ten() factory methods 
These methods are optimized for re-usability, and other methods now internally use them.

1420202440 Exact division algorithm is now in BigDecimal::dividedBy() 
BigRational::toBigDecimal() is now really just a proxy method to BigDecimal::dividedBy().

7eeb9d3ca0 Parameters to BigNumber methods must be convertible to the current type 
This applies to plus(), minus(), multipliedBy(), dividedBy().

b3371daab2 BigDecimal::dividedByWithRounding() is now dividedToScale()

65d4dd75d6 Rename BigRational factory methods 
- `BigRational::parse()` is now `of()`
- `BigRational::of()` is now `nd()`

This keeps BigRational in line with BigInteger and BigDecimal, whose `of()` factory method accepts a single parameter.
The new way to create a BigRational from two numbers is now called `nd()` for numerator/denominator.

321c00281d CS fixes 
Shorthand "int" and "bool" are now used instead of "integer" and "boolean".
This makes more sense as the latter are not accepted as synonyms in PHP 7 scalar type hints and return types.

c1aa379479 BigNumber is now an abstract class 
This allows the factorization of most comparison & sign functions in a single place.
Only `compareTo()` and `getSign()` are now abstract, the others methods are based on these two.
