k7 is a high precision calculator program that uses text input. It evaluates algrebraic expressions and has a crude "programming" capability. Its precision is variable up to 270 binary bits and 60 decimal digits, beyond the capability of a 80X87 floating point processor. k7 comes in two versions: a non-Windows version which has its own fixed size windows, and a Windows 3.1 and 95 version.
