Re[3]: Плавающая арифметика в системных потоках
Здравствуйте, Евгений Музыченко, Вы писали:

Упс, сорян, я люто наврал про супер скорость cpp_dec_float, это он побыстрее моего класса в два-три раза, от встроенного double он таки сильно отличается, но деление всего в 250 раз тормознее дабла, а у меня в 2500 раз.

Но можно поменьше знаков использовать, наверное, будет пошустрее, ну, и не обязательно десятичное, мне-то надо было для самописной бухгалтерии, поэтому завязывался на десятичку, но в бусте вроде есть и без такой привязки, должно быть пошустрее
