| DESCRIPTION |
calc is a calculator for doing real arithmetic using familiar infix
notation. calc uses a calculation method based on the popular program
VisiCalc in that it allows variables to be define by equations. For
example,
A = B + C * D
says that whatever B, C, and D are, A is equal to the above function
of them. If B, C, or D change, then so does the value of A because it
depends on them. (To set A to the value of a function of several
variables so that it doesn't change over time, you prepend a # before
the variable to indicate you want the current value.) In calc, you get
the prompt, "CALC: ", and you type in an expression to be calculated.
You can use numbers and even variables. For example,
12 + 123/6
a = b^2 + log (sqrt (c))
AVeryLongVariableName = (a+b) - c*d/e ^ f%log (sqrt (exp (abs (x))))
The usual operators and precedences are available along with the
common mathematical functions. Parentheses can be used for clarity.
