Single-Precision Mathematics

This section describes operations on single-precision numbers -- that is, numbers of type single. Because MATLAB stores numbers of type single using 32 bits, they require less memory than numbers of type double, which use 64 bits. However, because they are stored with fewer bits, numbers of type single are represented to less precision than numbers of type double.

This section covers the following topics:

• Data Type single
• Single-Precision Arithmetic
• The Function eps
• Example -- Writing M-Files for Different Data Types
• Largest and Smallest Numbers of Type double and single

Warnings for Integer Data Types
