A Credit-Card Sized Delight
The Canon FS-5 is a thin as a credit card calculators that came popular during the 1980s. Other calculators that belong to the credit card size are Casio fx-82 and TI-30 SLR. All the buttons are small, but are responsive, especially the small round clear all ([CA]) button.
The display is 8 digits (which reduces to 5 digits when powers of ten are displayed).
One thing to note, the power function is labeled by a^x.
The statistics package that the FS-5 offers is very simple: mean, sample deviation (labeled by σ^(n-1)), and population variance (labeled by v^n). You enter statistics mode automatically by pressing the [SUM] button and delete last entry by the [INV] [SUM] (DLT). To return to mathematics mode and clear all statistics registers, press the [CA] button.
The FS-5 run by solar power, with no battery backup. Be sure to be in adequate light.
This Calculator is Thin!
I think the picture below says it all:

This is a nice, thin, and simple scientific calculator. I like the key design, especially since the buttons are small, they are responsive. The calculator looks pretty cool too. If you can find one online, consider getting it. I paid $15, I think that is reasonable, somewhere in the teens.
Until next time,
