-----------------------------
Hi.
Asking questions or proposing new features is best done through the mailing
lists channel:
http://commons.apache.org/math/mail-lists.html
The bug tracking system is preferred for filing reports on identified bugs or
tasks to be performed (e.g. after they have been discussed on the "dev" mailing
list).
This kind of utilities is located in the "MathUtils" class (package
"org.apache.commons.math3.util").

> Is there a place here for basic but repeated methods such as:
> public static void verifyPositive(double number) {
> verifyBigger(number, 0, false);
> }
> public static void verifyTwoOrMore(double number) {
> verifyBigger(number, 2, true);
> }
> public static void verifyBigger(double number, double minimum,
> boolean isExactOK) {
> if (!isBigger(number, minimum, isExactOK)) {
> throw new IllegalArgumentException(number
> + (isExactOK ? "<" : "<=") + minimum);
> }
> }
> public static boolean isBigger(double number, double minimum,
> boolean isExactOK) {
> return number > minimum || isExactOK && number == minimum;
