1.8 Правила написания чисел

Основное различие при написании чисел в английских и русских текстах заключается в следующем:

-- в английском языке точка отделяет десятичные знаки от целых частей, а запятая отделяет разряды целых чисел;

-- в русском языке для этих целей используется запятая;

-- ноль может опускаться при написании английских десятичных дробей, большое количество нулей после точки в десятичных дробях может заменяться нулем в соответствующей степени (см. таблицу 1).
