|
|
|
|
|
|
|
|
|
|
- Update to v1.2
|
|
|
|
|
* Changes in this version include:
|
|
|
|
|
+ New features:
|
|
|
|
|
~ NUMBERS-206: "Selection": Add selection of the k-th ordered
|
|
|
|
|
element from an array.
|
|
|
|
|
~ NUMBERS-205: "Addition/Multiplication": Introduces isZero

|
|
|
|

~ NUMBERS-203: "DDField": Add a field for the DD number.
|
|
|
|
|
~ NUMBERS-193: "DD": Add an extended precision floating-point
|
|
|
|
|
number. A double-double (DD) number is an unevaluated sum
|
|
|
|
|
of two IEEE double precision numbers capable of
|
|
|
|
|
representing at least 106 bits of significand.
|
|

|
|
|
|
|
first kind.

|
|
|
|
Anirudh Joshi.
|
|
|
|
|
+ Changes:
|
|
|

|
|
|
|
|
Thanks to Matthias Langer.
|
|
|
|
|
~ "ArithmeticUtils": Improve performance of remainderUnsigned
|
|
|
|
|
and divideUnsigned. Thanks to Sebb, Alex Herbert.
|
|
|
|
|
~ NUMBERS-199: "Precision": Document inaccurate decimal value
|
|
|
|
|
representation when converting to and from a double in the

|
|
|
- Update to v1.1
|
2022-12-12 07:18:31 +00:00
|
|
|
* Changes in this version include:
|
|
|
|
|
+ New features:
|
|
|
|
|
~ NUMBERS-70: Add a user guide.
|
|
|
|
|
~ NUMBERS-190: Add a Bill of Materials (BOM) to aid in
|
|
|
|
|
dependency management when referencing multiple Apache
|
|
|
|
|
Commons Numbers artifacts. The BOM should be used to ensure
|
|
|
|
|
all imported artifacts are compatible.
|
|
|
|
|
~ NUMBERS-181: Updated support for the beta functions.
|
|
|
|
|
"RegularizedBeta": Added the complement and derivative of
|
|
|
|
|
the regularized beta function. Added "IncompleteBeta" and
|
|
|
|
|
"Beta" classes. Functionality is ported from the Boost C++
|
|
|
|
|
library.
|
|
|
|
|
~ NUMBERS-180: "GammaRatio": Compute the ratio of two gamma
|
|
|
|
|
functions.
|
|
|
|
|
~ NUMBERS-177: "Erfcx": Compute a scaled complementary error
|
|
|
|
|
function: erfcx(z) = erfc(z) * exp(z*z).
|
|
|
|
|
~ NUMBERS-175: "GeneralizedContinuedFraction": A continued
|
|
|
|
|
fraction class to compute using a generator. Allows
|
|
|
|
|
evaluation of continued fractions from a regular series
|
|
|
|
|
where coefficients can be computed iteratively from the
|
|
|
|
|
previous coefficients.
|
|
|
|
|
+ Fixed Bugs:
|
|
|
|
|
~ NUMBERS-185: "Precision": Allow Precision.compareTo using a
|
|
|
|
|
maxUlps to be used for sorting. This corrects handling of
|
|
|
|
|
NaN comparisons.
|
|
|
|
|
~ NUMBERS-182: "LogBeta": Avoid overflow for tiny arguments.
|
|
|
|
|
~ "BrentSolver": Avoid overflow creating the initial value
|
|
|
|
|
between the lower and upper.
|
|
|
|
|
~ NUMBERS-173: "ContinuedFraction": Set a minimum bound on
|
|
|
|
|
the relative error epsilon. Prevents an infinite loop when
|
|
|
|
|
the epsilon is zero.
|
|
|
|
|
~ "FactorialDouble": Prevent caching values that are
|
|
|
|
|
infinite. The cache will support factorials up to 170.
|
|
|
|
|
~ NUMBERS-170: "RegularizedBeta": Detect edge cases for
|
|
|
|
|
arguments that can be evaluated by exploiting properties of
|
|
|
|
|
the regularized beta function.
|
|
|
|
|
~ NUMBERS-168: "BrentSolver": Identify brackets with small
|
|
|
|
|
objective values.
|
|
|
|
|
~ Fix wrong javadoc. Thanks to Arturo Bernal.
|
|
|
|
|
+ Changes:
|
|
|
|
|
~ NUMBERS-184: "Precision": Reduce number of operations in
|
|
|
|
|
Precision.equals using a maxUlps.
|
|
|
|
|
~ NUMBERS-183: Improve the binomial coefficient classes.
|
|
|
|
|
Avoid recursive method calls. Avoid overflow for
|
|
|
|
|
BinomialCoefficientDouble for large results close to
|
|
|
|
|
infinity. Use precomputed factorials and the LogBeta
|
|
|
|
|
function for efficiency.
|
|
|
|
|
~ NUMBERS-178: "Factorial/FactorialDouble": Tabulate all
|
|
|
|
|
factorials with exact 64-bit double representations of n!
|
|
|
|
|
up to n=170. This change deprecates the FactorialDouble
|
|
|
|
|
class and removes obsolete caching functionality.
|
|
|
|
|
~ NUMBERS-176: "ContinuedFraction": Update to use a shared
|
|
|
|
|
implementation with GeneralizedContinuedFraction.
|
|
|
|
|
~ NUMBERS-174: "Gamma/LogGamma/RegularizedGamma": Update the
|
|
|
|
|
gamma function implementations to increase accuracy and
|
|
|
|
|
support for extreme values. Functionality is ported from
|
|
|
|
|
the Boost C++ library.
|
|
|
|
|
~ NUMBERS-172: "Erf/Erfc": Use a rational function
|
|
|
|
|
approximation accurate to 53-bits of precision. This
|
|
|
|
|
replaces the use of the regularized gamma functions P and Q
|
|
|
|
|
and increases accuracy at extreme limits of the function.
|
|
|
|
|
Execution speed is improved. Functionality is ported from
|
|
|
|
|
the Boost C++ library.
|
|
|
|
|
~ NUMBERS-171: "InverseErfc": Support full range of [0, 2].
|
|
|
|
|
This lowers the supported minimum value from 2^-53 to
|
|
|
|
|
double min value. Execution speed is improved.
|
|
|
|
|
Functionality is ported from the Boost C++ library.
|
|
|
|
|
- Add build dependency on
|
|
|
|
|
mvn(org.apache.commons:commons-rng-bom:pom:)
