MATLAB represents floating-point numbers in double precision. Double precision allows you to represent numbers to greater precision but requires more memory than single precision. To conserve memory, you can convert a number to single precision

Floating-point numbers are analogous to scientific notation. They circumvent the limitation of having a constant number of integer and fraction bits, allowing the representation of very large and very small numbers. Like scientific notation, floating-point numbers have asign,mantissa(M),base(B), an...
