Conversion Between Symbolic and Numeric. Convert symbolic data to numerics, convert numerics to symbolic objects. Symbolic Math Toolbox™ lets you convert data between symbolic and commonly used MATLAB ® data types. You can also perform numeric computations with high precision using variable-precision arithmetic.

Symbolic numbers are exact while double-precision numbers have round-off errors. Convert pi and 1/3 from symbolic form to double precision. symN = sym ( [pi 1/3]) symN = [ pi, 1/3] doubleN = double (symN) doubleN = 3.1416 0.3333. For information on round-off errors, see Recognize and Avoid Round-Off Errors.
