Simplification of expressions containing piecewise functions has been improved.
|
Equal, equivalent, or implied piecewise branches are now combined by simplify;
Piecewise conditions involving floor, ceil, round, frac, trunc can now be simplified:
Branch conditions other than equations, inequations, and inequalities are now taken into account while simplifying branch values:
Branch conditions are now simplified more effectively using basic boolean logic:
simplify now reorders piecewise conditions when appropriate:
Piecewise conditions are now better normalized;
Common terms and factors are now pulled out of piecewise branch values where possible:

Expressions containing csgn can now be more effectively simplified:
Conversion between powers, exponentials, trig functions, and radicals to achieve simplification has been improved:
Symbolic powers of integers are now combined more effectively:
simplify now rewrites expressions using a common integer base:
Radicals are now typically combined by simplify:
If appropriate conditions are satisfied, certain simplifications of floor, ceil, and round are applied:
now simplifies:
