- DOCUMENTATION FOR HCALC.COM
- (MS-DOS)
-
- The program named CALCULATOR by Warren Smith and converted to
- TURBO PASCAL has been renamed to HCALC.COM. This is a stan-
- dard algebraic style program without the use of equal signs.
-
- The program is booted in by typing HCALC <cr>. In order to
- get help, type: ? To exit to MS-DOS, at the beginning of a
- line, type: $
-
- In addition to all of the standard operands + - * and /, you
- can use trig functions, square roots, squares, factorials and
- PI. Except for PI, to get the values sought after, you must
- follow the proper syntax.
-
- The proper syntax is to enclose the value to be operated upon
- within parenthesis () preceeded by the operator. (You may
- use upper or lower case at will).
-
- Examples are shown below:
-
- sqr (4)<cr> answer will be 16.0000
- SQRT (64)<cr> answer will be 8.0000
- factor (7)<cr> answer will be 5040.0000
- SIN (45)<cr> answer will be 0.707
- pi<cr> answer will be 3.14159
-
- When using terms with exponents, show them as follows:
-
- (3*10^6)*(4*10^9)<cr> answer will be 11.9999999999999990
-
- (The 10^6 represents ten to the sixth power. You must indi-
- cate the power of ten you want use in the expression.)
-
- If you do not enclose the value within parenthesis, the pro-
- gram will not work and you will get wrong answers. Also if
- you type: !<cr> you will go into the debugging mode and the
- intermediate steps of the calculation will be displayed prior
- to the answer. To stop debug mode type !<cr> at the begin-
- ning of a line and this will toggle it off.
-
- You may utilize these operations as part of the expression to
- be solved.
