<p>A real single precision data type specifies how a real number, or an approximation of a real number is stored in memory that occupies one word in computer memory, where the byte length of a word depends on machine address size of the computer processor.
For example, on 32-bit machine architectures, a word is four bytes.
An example of a real single precisoin data type specification is the IEEE 754 standard for encoding binary or decimal floating point numbers in 4 bytes for storage on 32-bit machine architectures.
