Moon Phase Calculation 1.0   (details) 49/50 ENG   98 KB / 2 KB
ScreenshotMoon is a small program to calculate and display the moon phases. It uses the drawing routines provided by Craig Finseth's phase of the moon program (with the modifications to FLIP as suggested by Preston Brown and Juri Munkki), but has an adapted version of the very complicated phase calculation in John Walker's moontool application on the SUN.

TVM (Gerson)   (details) 48 ENG   3 KB / 2 KB
Yet another version of the TVM calculations available on HP's financial calculators (the TVM equation was copied from the HP-12C manual). This displays all the variables' values when any are changed, and permits you to solve for any unknown given the other values. It also supports different number of compounding periods per year, giving annualize displays and inputs for the number of payments and interest rates.
