Numbers and Precision
The Symbolic Math Toolbox™ can perform numeric calculations
with variable precision by using
For details, see Increase Precision of Numeric Calculations. To understand
when to use symbolic, variable-precision, or double-precision arithmetic,
see Choose Numeric or Symbolic Arithmetic.
The Symbolic Math Toolbox also provides functions for rounding
operations and for working with complex numbers.
Compare and contrast double-precision, variable-precision, and symbolic arithmetic.
Convert floating-point numbers to exact symbolic numbers.
Increase precision arbitrarily with variable-precision arithmetic.
Round-off errors in symbolic and variable-precision calculations.
Increase speed of calculations by reducing precision of calculations.
