Difference between Integer and Double. Integer is used as a data type to denote an integer number, whereas double is a data type to denote a big floating number. Programming languages consist of various types of data types like int, float, double, etc. Integers can be generally described as types of whole numbers that are not in a form of fraction.

SQL Data Types. They may sound like menu items at a malt shop, but real, float, and double are data types supported by SQL and other programming languages. Once you learn these, you’ll have a good foundation for other tools as well. Each data type is considered an approximate value because their usage in SQL revolves around precision.

Numeric data has mode « numeric, » but it has one of three types: integer, single precision, and double precision. Most numbers in S-Plus is represented in double precision, called double in R. Single precision (called « float » in C) uses less memory, so I suppose you could save memory in a really big matrix by keeping it in single precision, but R tends to converts singles to doubles when it’s computing anyway.

Double-precision floating-point format is a computer number format, usually occupying 64 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. Floating point is used to represent fractional values, or when a wider range is needed than is provided by fixed point (of the same bit width
