@ -3227,8 +3227,18 @@ A reasonably powerful calculator based on zsh's arithmetic evaluation
facility. The syntax is similar to that of formulae in most programming
languages; see
ifzman(the section `Arithmetic Evaluation' in zmanref(zshmisc))\
ifnzman(noderef(Arithmetic Evaluation)) for details. The mathematical
library tt(zsh/mathfunc) will be loaded if it is available; see
ifnzman(noderef(Arithmetic Evaluation)) for details.
Non-programmers should note that, as in many other programming
languages, expressions involving only integers (whether constants
without a `tt(.)', variables containing such constants as strings, or
variables declared to be integers) are by default evaluated using
integer arithmetic, which is not how an ordinary desk calculator
operates. To force floating point operation, pass the option tt(-f);
see further notes below.
The mathematical library tt(zsh/mathfunc) will be loaded if it is
available; see
ifzman(the section `The zsh/mathfunc Module' in zmanref(zshmodules))\
ifnzman(noderef(The zsh/mathfunc Module)). The mathematical functions
correspond to the raw system libraries, so trigonometric functions are
