| Summary : parses, compiles and evaluates mathematic expressions
|
Description :
Math::Expression::Evaluator is a parser, compiler and interpreter for
mathematical expressions. It can handle normal arithmetics (includings
powers wit \'^\' or \'**\'), builtin functions like sin() and variables.
Multiplication \'*\', division \'/\' and modulo \'%\' have the same precedence,
and are evaluated left to right. The modulo operation follows the standard
perl semantics, that is is the arguments are castet to integer before
preforming the modulo operation.
Multiple exressions can be seperated by whitespaces or by semicolons \';\'.
In case of multiple expressions the value of the last expression is
returned.
Variables can be assigned with a single \'=\' sign, their name has to start
with a alphabetic character or underscore \'[a-zA-Z_]\', and may contain
alphabetic characters, digits and underscores.
Values for variables can also be provided as a hash ref as a parameter to
val(). In case of collision the explicitly provided value is used:
$m->parse(\"a = 2; a\")->val({a => 1});
will return 1, not 2.
The following builtin functions are supported atm:
* *
trignometric functions: sin, cos, tan
* *
inverse trigonomic functions: asin, acos, atan
* *
Square root: sqrt
* *
exponentials: exp, sinh, cosh
* *
logarithms: log, log2, log10
* *
constants: pi() (you need the parenthesis to distinguish it from the
variable pi)
* *
rounding: ceil(), floor()
* *
other: theta (theta(x) = 1 for x > 0, theta(x) = 0 for x < 0)
