Returns the instance of {@link MathVariable} if the variable exists on {@link #getVariables()} or {@link #getInnerVariables()}, Null otherwise.

Parses and calculates the expression @param expression the expression to parse and calculate @throws MathParserException If somethi

Calculates and returns the value Parameters are usually double values

Adds a new variable to this {@link MathParser} @param name variable name @param expression expression of variable @see #addVariable(String, dou

Adds a const variable to {@link #innerVariables};

Creates a new copy of this {@link MathParser} @return a shallow copy of this {@link MathParser} @noinspection MethodDoesntCallSuperMethod

@return True if src is an special characters, False otherwise

Removes the specified variable from {@link #getVariables()}

Calculates and returns the value of an expression @param exp the simplified expression @param main the original expression

Returns the list of imported variables

Calls when this function just attached to a parser or it's parent variable called to calculate

@return True if name mentions this function

Simplify syntax for common functions

@return the name of function

Rounds the value if {@link #roundEnabled} is true. @see #setRoundEnabled(boolean) @see #isRoundEnabled()

Because of the way floating-point numbers are stored as binary, it is better to round them a bit <p> Some functions like {@link Functions#derivative(M

validate syntax

Adds support of an expression to this {@link MathParser}, the expression must contains {@code =}, There are two types of phrases. Variable and Functio

Adds a new function to this {@link MathParser} @see #addExpression(String)

Calculate the answer of variables

Couldn't find the variable but let's try to guess what could it be, may help to debug the expression

(0b010) -> (2)

Makes degrees readable for Math trigonometry functions x° => toRadians(x)

(2e+2) -> (200.0)

Makes factorial readable x! => factorial(x)

(0x0FF) -> (255)

(0o027) -> (23)

java.org.apache.commons.lang3.StringUtils#getLevenshteinDistance(CharSequence, CharSequence)

Adds default constants {pi, e}

@return True if src exists on supported operations, False otherwise

@return True if the parameter at specified index won't be a double value (String otherwise)

{@link #calculate(String, String, boolean)} has simplified the expression as much as it's possible, It is time to set priorities of {@link #operations

@see jdk.internal.joptsimple.internal.Strings#repeat(char, int)

Calculates the similarity (a number within 0 and 1) between two strings. https://stackoverflow.com/a/16018452/9187189

so there is a string which isn't a number, this function will try to parse this word and check for variables "xy" => can be two variables (x or y) or

@param src the expression to check @throws BalancedParenthesesException If parentheses aren't balanced
