What are decimals? - BBC Bitesize.
A decimal separator is a symbol used to separate the integer part from the fractional part of a number written in decimal form. Different countries officially designate different symbols for use as the separator. The choice of symbol also affects the choice of symbol for the thousands separator used in digit grouping. Any such symbol can be called a decimal mark, decimal marker or decimal sign.
If you needed to log the same number to the thousandth place, which is the third place to the right of the decimal point, you write 5.000 and so on. This works the same with any whole number, going to any number of places after the decimal point because there are understood to be an infinite number of spaces after the decimal, and in the case of a whole number, each space is filled by a zero.
