Converting currency into words for billing in Russia.

Class used only integer operations to avoid floating point misunderstanding, because it cannot represent an arbitrary decimal fractions exactly. Floating point shouldn't be used for anything that requires exactness.

This is a library, not an apllication.

Usage

echo JagmortCurrencyNumericToWords::createInstance()->convert('12345.67')

# will print
> двенадцать тысяч триста сорок пять рублей 67 копеек
