A small calculator can be useful to evaluate a single formula involving a few parameters/variables. This formula calculator class constructs a small calculator which evaluates the formula or its inverse with respect to a particular parameter, according to specified code for each result.
Step 1: Enter the expression you want to evaluate. The Math Calculator will evaluate your problem down to a final solution. You can also add, subtraction, multiply, and divide and complete any arithmetic you need. Step 2: Click the blue arrow to submit and see your result!
This is a small 4-function-calculator. It uses expr directly to calculate the results, so you may need to append ".0" to numbers to do calculations in floating point. E.g. "3/2" will be done on integers: "3/2=1", so you might want to do "3/2.0" instead.
17 sty 2012 · $ tclsh calc.tcl >> f(x y)= $x > $y ? $x : $y f >> f(2,3) 3 >> f(5,1) 5 >> g(x)=$x*2 g >> 1 + g(5) 11 Explanation: I used an Itcl class to create a reusable calculator. The eval method evaluates expressions, and if the expression is a function it will define it in tcl::mathfunc namespace, so that it's available in expr .
