Detailed Description

Mathematical expression parser.

This class interprets mathematical expression strings (e.g. "2+3") and returns the result of the calculation. It is actually only a wrapper around the muparser library, so take a look at its documentation for details.

Constructor & Destructor Documentation

MathParser() [1/2]

MathParser ( )

noexcept

Here is the caller graph for this function:

Member Function Documentation

setLocale()

void setLocale ( const QLocale &  locale )

noexcept

Set the locale to be used for parsing numbers.

This sets the thousand separator and decimal point to be used for the evaluation.

Parameters

locale

The locale to use.

Here is the caller graph for this function:

parse()

MathParser::Result parse ( const QString &  expression ) const

noexcept

Parse expression.

Parameters

expression

The expression to parse.

Returns

The result, either valid with a value, or invalid with an error message.

Here is the caller graph for this function:

operator=()

MathParser& operator= ( const MathParser &  rhs )

delete
