 Evaluate expression @var{expr} while the expression @var{cond} is
 non-zero, and returns the value of the last @var{expr} evaluation, or
 NAN if @var{cond} was always false.

+Round the value of expression @var{expr} upwards to the nearest
+integer. For example, "ceil(1.5)" is "2.0".

 In your C code, you can extend the list of unary and binary functions,
 and define recognized constants, so that they are available for your
 expressions.
