Symbolic numbers are exact, while double-precision numbers have round-off errors. Variable-precision numbers created by vpa are symbolic values.

Help Center Help Center. You cannot change the default type and precision. You can choose to store any number, or array of numbers, as integers or as single-precision. Integer and single precision arrays offer more memory-efficient storage than double precision. All numeric types support basic array operations, such as indexing, reshaping, and mathematical operations. The default is double precision. If you use the smallest integer type that accommodates your data, you can save memory and program execution time.
