I want to vale on the word document. In workspace the value is symbolic fform.

In the past I have posted code for replacing small symbolic constants. Help Center Help Center.

Help Center Help Center. When you choose variable-precision arithmetic, by default, vpa uses 32 significant decimal digits of precision. For details, see Choose Numeric or Symbolic Arithmetic. You can set a higher precision by using the digits function. Approximate a sum using the default precision of 32 digits. If at least one input is wrapped with vpa , all other inputs are converted to variable precision automatically. You must wrap all inner inputs with vpa , such as exp vpa

Help Center Help Center. If you do not specify var , vpasolve solves for the default variable determined by symvar. By default, vpasolve finds the solutions to 32 significant digits. To change the number of significant digits, use the digits function. This syntax returns a structure array Y that contains the solutions. The fields in the structure array correspond to the variables specified by vars. If you do not specify vars , vpasolve solves for the default variables determined by symvar.

Help Center Help Center. For differences between symbolic and double-precision numbers, see Choose Numeric or Symbolic Arithmetic. Convert symbolic numbers to double precision by using double. Symbolic numbers are exact, while double-precision numbers have round-off errors. Variable-precision numbers created by vpa are symbolic values. When a MATLAB function does not accept symbolic values, convert variable precision to double precision by using double.

Productos Symbolic Math Toolbox. Remember that the number of digits can change, and the number of digits can be specified in the vpa call. Save the old value of digits returned by digits 7. Documentation Examples Functions Videos Answers. Why not just copy and paste it into the word document? Thanks in advance. By default, vpa calculates values to 32 significant digits. The differences between the symbolic approximations of pi become more visible. Other MathWorks country sites are not optimized for visits from your location. Respuesta aceptada: Walter Roberson.

The previous expressions will be evaluated as floating point, therefore they will lose precision. Remember that the number of digits can change, and the number of digits can be specified in the vpa call. Evaluate symbolic inputs with variable-precision floating-point arithmetic.
