NAME

Spreadsheet::Engine::Function::math2 - base class for 2arg math functions

SYNOPSIS

  use base 'Spreadsheet::Engine::Function::math2';

  sub calculate { ... }

DESCRIPTION

This provides a base class for spreadsheet functions that perform mathematical functions with two arguments (POWER(), MOD(), etc)

Subclasses should provide 'calculate' function that will be called with the arguments provided.

INSTANCE METHODS

execute

This checks that the parameters passed to the function are correct, and if so delegates to the subclass to calculate().

calculate

Subclasses should provide this as the workhorse. It should either return the result, or die with an error message (that will be trapped and turned into a e#NUM! error).
