KoalaCalc is a free multi-purpose calculator for Mac OS X. In its compacted state, it looks similar to the standard calculator that comes with Mac OS X. However, simply click the 'advanced features' box and KoalaCalc comes to life to become one of the most advanced scientific, conversion, statistical and expression calculators available.

The list of features includes:
  • Numerous mathematical functions including trig and log functions plus 10 individual memory banks
  • Conversion to and from dozens of units (inches to millimeters, pounds to kilograms, etc.)
  • Basic
What's New
Version 4.5.2:
  • Fixed bug which caused speech problems under Mac OS X 10.7 (Lion)
Requirements
PPC / Intel, Mac OS X 10.4 or later.

I downloaded KoalaCalc out of curiosity to see the fractions feature. It installed itself as root! All of my attempts to change its owner and group (via the Finder, Path Finder and the terminal) have failed since it immediately switches back to root, so I can't even move it to the trash. There is absolutely no reason why a calculator program should be installing itself this way.

I finally managed to change the permissions (by changing theACL), and deleting KoalaCalc. I hope that the author corrects this.

Sorry about that. There was a glitch in the version 4.5.1 installer. I have updated it so that it now installs with regular user permissions. I just happened to stumble upon this bug report here. In the future please report bugs to the tech support e-mail address on the Macropod Software website at www.macropodsoftware.com. Otherwise it might never get fixed.

A "glitch" that creates an ACL huh? Must be another sign of 'the end of times'. ;)

Not sure what is being implied here. I used XCode's Packagemaker app to create the installer as recommended by Apple and had the permissions of the installed files set to root as owner and the group admin. To delete the file, you simply drag to the trash and enter your admin credentials when prompted. As reported above, the installer settings have now been changed so that the files are installed using the user name as the owner.

I d/l the zip file here and got operation not permitted. I then went to the Developer's web site and got the same results.

It's great to see this gem updated. I used it regularly many years ago. I eventually replaced it with PCalc, but KoalaCalc was quite good and free (open to donations).
Nice to see it's still being supported.

Awesome!

The fraction part is really well designed. That saves the hassle of paper.

A graphic artist needs to make them a new icon though! Must be someone who will donate one that uses this.

A Great Product. Fantastic for those who like Apple's own calculator but need that extra "Oomph". Highly Recommended.

Last I heard, 6+14÷5-3=5.8, but in Simple mode, KoalaCalc told me that 6+14÷5-3=1! Hmm!

KoalaCalc is a linear calculator so it deliberately ignores order of operations and brackets when they are not printed on the screen as this can lead to confusion. Thhat is, operations are processed in the order they are entered.

For order of operation calculations and brackets, use the built-in expression calculator by clicking the "Expression" tab when the calculator is in advanced mode. The expression calculator was designed speciifically for the feature you requested.

The following changes were made to 4.3 (available on the included version history file):

currency exchange rates are now served directly from Macropod Software to greatly improve availability of exchange rates
memory buttons now visible in simple mode at startup if user selects this preference setting
changed functionality of percent key: for example, to subtract 25% from 200, enter 200-25%=
added units for constants in constants menu
fixed bug where KoalaCalc could appear off screen when switching to a lower screen resolution
fixed bug which printed the wrong symbol in the tape when the divide key was pressed
button help information no longer inappropriately appears when pointer hovers overs memory storage banks after pressing M+, M- or MR keys

Please don't distribute it as a StuffIt archive. With Tiger ommitting expander it's become a pain.

Tiger is by far the lowest Mac OS in population - and Stuffit Expander 9.0.2 is bug-free, easily obtainable, and FREE.

Horse manure! And just where do you get your figures to back up that preposterous statement? Every poll I have seen shows that Panther has been all but left behind.
