With the new Version I changed to Launch Icon to follow the official Design guide for Material-Design:

• Bold and simple design with little detail.
• a small shadow.

This icon should fit more into the overall design of an android system.

So what do you think, which Icon do you prefer?

Poll will be closed 11.Jan.2015

A typical binary floating point error. While humans use exponents to the power of 10 (×10ˣ) many computer use exponents to the power of 2  (×2ˣ). But with an power of 2 exponent many decimal fraction can not be represented causing rounding mistakes then the number need to be printed in decimal.

That is why I (like any proper calculator) use BCD floating points. That is I calculate in decimal and with  exponents to the power of 10 so I can present proper results to my human users.
 
Weird random Android 5.0 calculator bug :o

Have Android 5.0? Try it.

A hint of material design.

Of course only a hint as a the Simulator does not lend itself to the rules of material design

If you don't want to wait for Sunday so join the community and the beta program.
 
New Version out beta test. This is also a release candidate to be released on Sunday.

You might not notice any difference but the Buttons have been redone to use fewer resources resulting in less lag and memory usage.

There has been reports on lag when using the +FX-603P Simulator or the +HP-45 Emulator on the +Nexus 4. This Video shows that there is no lag what's however.

A scientific calculator based on the classic HP-45 calculator.
Introduction
HP-45 Emulator is a true hardware emulation of the classic HP-45 and will behave just like the original. Of course the emulator is fully usable as a scientific calculator.
