variable-precision arithmetic and elementary number-theoretic operations

the symbolic math toolbox™ can perform numeric calculations with variable precision by using . for details, see . to understand when to use symbolic, variable-precision, or double-precision arithmetic, see . the symbolic math toolbox also provides functions for rounding operations and for working with complex numbers.

numerical integration using variable precision
solve symbolic equations numerically
numerical summation using variable precision
imaginary part of complex number
real part of complex number
convert symbolic integer in decimal to binary representation
