NAME

App::Math::Tutor::Role::FracExercise - role for exercises in calculation with units

ATTRIBUTES

relevant_units

Specifies relevant units. Option argument can be either a list of units to take care, or starting with an exclamation mark, a list of units to skip.

Known units contain time, length, weight, euro, pound, dollar.

unit_length

Allowes one to limit the "length" of a unit. While some unit categories have many entries (e.g. time - which can result in ${a} w ${b} d ${c} h ${d} min ${e} s ${f} ms) - limiting the length would result in not more than ${unit_length} elements per number.

deviation

When more than one operand is involved, control deviation using this option. Best results with unit_length.
