"float" should be sufficient
String is not appropriate for that. While it is possible to store a number in a string, additional conversions need to be done if you need the number for calculations. Instead, use an integer data type (if no decimals are required), or a real data type (if decimals are required). In Java, for example, you could use int (no decimals) or double (allows decimals).

An array.

EDO stands for 'extended data out'. Its a type of memory/RAM.

Depending on the type of chart, different things can represent data. Pie slices on pie charts, bars on bar charts and columns on column charts for example.
I am assuming that the question is "What would the best data type to represent a price".Although this is open for debate, in Java I think that the best data type for a price is double and the best data type in C# to be decimal.I hope this answers your question.
