Stefano Sabatini e4e291061c doc/eval.texi: add precisation about the assumption for "trueness" in conditional expressions 2012-01-17 12:03:30 +01:00
Stefano Sabatini 999495734b lavu/eval: add if() and ifnot() eval functions 
They allow to implement the if/then/else logic, which cannot be
implemented otherwise.

For example the expression:
A*B + not(A)*C

always evaluates to NaN if B is NaN, even in the case where A is 0.
