- Pick up the file ICALC.TXT via anonymous ftp from moose.cccs.umn.edu
- [128.101.133.53] and follow the instructions contained therein.
-
- If you do not have FTP access, please contact me somehow with some form
- of
- e-mail/paper-mail address, and I'll post it to you personally.
-
- ICALC is a simple, portable infix calculator which compiles on
- VMS, Unix and DOS with no changes required (for most "standard"
- C environments).
-
- Features:
- ~~~~~~~~
- 1) Addition (+), Subtraction (-), Multiplication (*), Division (/)
-
- 2) Modulus (%), Power (^)
-
- 3) Bitwise logical operators: bitwise AND (&), bitwise inclusive
- OR (|), unary one's complement (~)
-
- 4) 20 Math/Trigonometric functions: sin, cos, tan, asin, acos,
- atan,
- sinh, cosh, tanh, exp (exponentiation), ln (natural log),
- log (base 10 log), sqrt (square root), ceil (ceiling), floor,
- int/trunc (truncation), abs (absolute value),
- degtorad (degrees->radians), radtodeg (radians->degrees).
-
- Two Date functions to convert between calendar dates and julian
- days: caltojul (calendar->julian date) and jultocal
- (julian->calendar date).
-
- One '?'-for-help command to display a help screen of all
- supported commands and functions.
-
- 5) Temporary variables (as many as you want, with names as long as
- you want) to store intermediate computations.
-
- 6) This is a "portable" calculator in the sense that it's not
- specific to any operating system. The yacc output should be
- compilable by any C compiler; this program has been tested on
- Unix, VAX/VMS and PC/MS-DOS, and has required no changes to
- compile.
-
- 7) This program uses the simplest of input and output formats, and
- is in no way hardware dependent. So, as long as it compiles
- without any problems, there are no other requirements for it to
- work properly.
-
- 8) All numbers are of the C floating-point type "double", which,
- according to the VAX C manual, has a range of 0.29*10^-38 to
- 1.7*10^38, and has values precise to 16 decimal digits.
-
- 9) Allows any number of expressions on a line, separated by ';'
-
- 10) icalc can now be run either interactively (when it is
- invoked without any arguments, in which case the user is
- prompted for input) or in a command-line mode (when all
- expressions to be computed are passed to icalc via
- command-line "argv" arguments, in which case icalc computes
- and prints the result of each expression -- exactly as if
- it had been entered interactively -- and then exits).
- In the latter case, the user is supposed to delimit/
- separate the expressions by ';'
