ProCalc is Now CalcWorks

by Geoff Duncan

ProCalc is Now CalcWorks -- If you've been looking for new versions of the popular Calculator replacement ProCalc, you've been looking in all the wrong places. Beginning with version 1.4.0, author John Brochu <> has changed the name of his handy shareware program to CalcWorks to avoid a naming conflict with another product. But make no mistake: this award-winning desktop calculator is still around and better than ever. CalcWorks features full scientific and binary function sets, a printable paper tape window, optional RPN support (100 percent HP-compatible with pop-up stack display), customizable constants and conversions, a built-in help system (including a well-done Balloon Help), plus an easy-to-customize interface (put any calculator button anywhere you want). You can paste in equations for quick evaluation, enter figures directly in appropriate units (minutes, feet, degrees, etc.) and - thanks to a new floating point library - CalcWorks has floating point precision significantly better than most Mac applications (just try entering (1 - 0.9 - 0.1) in the standard Calculator and see what you get!). CalcWorks 1.4.2 can be located on most online services and at the following URL: [GD] works-142.hqx
