KCalc 1.8.1 has a number of trigonometric, statistics, logic, and exponential functions along with a number of built-in constants for science and engineering computations. KCalc 1.8.1 does seems to be pretty handy for these types of calculations.

However, I think that the number of KDE users who need or want to use financial functions is probably at least equal to the number of KDE users who need or want the math, science, and engineering functions which are designed into KCalc 1.8.1. Perhaps more importantly, the former category probably is growing a lot faster than the latter category as more and more people begin to use open-source software.

I therefore suggest that KCalc could be made even more useful to KDE users if it were re-designed as a small basic application with optional modules for additional functions. The basic KCalc application could include nothing more than simple functions found on the most basic calculators (i.e. the current functions in 1.8.1 without any of the optional settings). Optional KCalc modules could include the following:
> financial functions
> statistics functions
> science and engineering functions and constants
*--- Can other forum users suggest any others? ---*

The financial module functions would include at minimum basic compounding solving (see Poor Man's Financial Calculator project) and nominal <--> effective interest rate conversion. The KCalc developers could add some additional useful functionality by making something like 10 registers available for limited NPV and IRR calculations with uneven amounts.

The statistics module could also use about 10 registers for limited calculations.
