Since there are three zeroes after dot it mean 24 thousands. 24.000
In central Europe or in any country in Europe I visited dot is used to separate thousands and comma to mark decimal. If you want display partial of 1 when displaying price you use two - like one euro twenty four cents 1,24
If I want to type one million twenty four hundred thousands I type 1.240.000,00
In USA you would type 1,240,000.00
However internationally proper separation of big numbers is just leave space after every three digit.
From wiki:
In representing large numbers, English texts use commas (or spaces) to separate each group of three digits. This is almost always done for numbers of six or more digits, and optionally for five (or even four) digits. However, in much of Europe, Southern Africa and Latin America (and in South Africa) the comma is used as a decimal separator, equivalent to the decimal point. In addition, the comma may not be used for this purpose at all in some number systems, e.g. the SI writing style,[13] and a space may be used to separate every three digits instead.
