The symbol used to separate the integer part of a decimal number from its fractional part is called the decimal point. In the United States, the decimal point is denoted with a period (e.g., 3.1415), whereas a raised period is used in Britain (e.g., 3·1415), and a decimal comma is used in continental Europe (e.g., 3, 1415). The number 3.1415 is voiced "three point one four one five, " while in continental Europe, 3, 1415 would be voiced "three comma one four one five."
