You can evaluate most symbolic results numerically by inserting the numerical equal sign after the symbolic result.

A few symbolic results contain special symbolic functions or constants that you cannot evaluate with the numerical equal sign. To evaluate these functions, use the symbolic evaluation operator with the keyword float, which performs symbolic floating-point evaluation. For example, you can evaluate the symbolic function Zeta, which calculates the Riemann Zeta function, to 7 digits as follows:

Symbolic floating point evaluation is useful in cases where PTC Mathcad cannot return a result through traditional evaluation, such as with very large results, such as evaluating the Gamma function Γ at 100 or Γ(100).
