Method Summary

Modifier and Type	Method and Description
static boolean	checkIfCanonicalRounding() Double floating-point precision arithmetic causes rounding problems, i.e. 0.1 + 0.1 + 0.1 is slightly different than 0.3, additionally doubles are having a lot of advantages providing flexible number representation regardless of number size. mXparser is fully based on double numbers and that is why is providing intelligent canonical rounding to minimize misleading results.
static void	consolePrint(Object o) Prints object.toString to the Console
static boolean	isCurrentCalculationCancelled() Check whether a flag to cancel current calculation process is set.
static boolean	regexMatch(String str, String pattern) Function used to introduce some compatibility between JAVA and C# while regexp matching.

Method Detail

checkIfCanonicalRounding

public static final boolean checkIfCanonicalRounding()

Double floating-point precision arithmetic causes rounding problems, i.e. 0.1 + 0.1 + 0.1 is slightly different than 0.3, additionally doubles are having a lot of advantages providing flexible number representation regardless of number size. mXparser is fully based on double numbers and that is why is providing intelligent canonical rounding to minimize misleading results. By default this option is enabled resulting in automatic rounding only in some cases. Using this mode 2.5 - 2.2 = 0.3

Returns:

True if Canonical rounding is enabled, otherwise false.

consolePrint

public static final void consolePrint(Object o)

Prints object.toString to the Console

Parameters:

o - Object to print

regexMatch

public static final boolean regexMatch(String str,
                                       String pattern)

Function used to introduce some compatibility between JAVA and C# while regexp matching.

Parameters:

str - String

pattern - Pattern (regexp)

Returns:

True if pattern matches entirely, False otherwise

isCurrentCalculationCancelled

public static final boolean isCurrentCalculationCancelled()

Check whether a flag to cancel current calculation process is set.

Returns:

true in case cancel calculation flag is active, otherwise false
