Equation Functions The following table lists the functions that are valid in equations. Appendix G, "Operation Index" also gives this information. LN LOG EXP ALOG SQ SQRT INV IP FP RND ABS x!

The prefix functions that require two arguments are %CHG, RND, XROOT, IDIV, RMDR, Cn,r and Pn,r. Separate the two arguments with a colon. In an equation, the XROOT function takes its arguments in the opposite order from RPN usage. For example, -8 3 to is equivalent to %!1(.2. All other two-argument functions take their arguments in the Y, X order used for RPN. For example, 28 4 { \ is equivalent to Q8T1(2. For two-argument functions, be careful if the second argument is negative. For a number or variable, use ^ or . These are valid equations: Entering and Evaluating Equations 6-15
