This chapter describes the Calc commands for doing simple calculations on numbers, such as addition, absolute value, and square roots. These commands work by removing the top one or two values from the stack, performing the desired operation, and pushing the result back onto the stack. If the operation cannot be performed, the result pushed is a formula instead of a number, such as `2/0' (because division by zero is illegal) or `sqrt(x)' (because the argument `x' is a formula).
Most of the commands described here can be invoked by a single keystroke. Some of the more obscure ones are two-letter sequences beginning with the f ("functions") prefix key.
See section 4.7 Numeric Prefix Arguments, for a discussion of the effect of numeric prefix arguments on commands in this chapter which do not otherwise interpret a prefix argument.
