For convenience, prefix–type functions, which require one or two arguments, display
a left parenthesis when you enter them.
The prefix functions that require two arguments are %CHG, XROOT, IDIV, RMDR,
nCr and nPr. Separate the two arguments with a comma.
In an equation, the XROOT function takes its arguments in the opposite order from
RPN usage. For example, –8
All other two argument functions take their arguments in the Y, X order used for
RPN. For example, 28
For two argument functions, be careful if the second argument is negative. These are
valid equations:
