Unit.
evalf
(n=15, subs=None, maxn=100, chop=False, strict=False, quad=None, verbose=False)¶Evaluate the given formula to an accuracy of n digits. Optional keyword arguments:
- subs=<dict>
- Substitute numerical values for symbols, e.g. subs={x:3, y:1+pi}. The substitutions must be given as a dictionary.
- maxn=<integer>
- Allow a maximum temporary working precision of maxn digits (default=100)
- chop=<bool>
- Replace tiny real or imaginary parts in subresults by exact zeros (default=False)
- strict=<bool>
- Raise PrecisionExhausted if any subresult fails to evaluate to full accuracy, given the available maxprec (default=False)
- quad=<str>
- Choose algorithm for numerical quadrature. By default, tanh-sinh quadrature is used. For oscillatory integrals on an infinite interval, try quad=’osc’.
- verbose=<bool>
- Print debug information (default=False)
