### 5 Band Resistor Calculator

Posted: Sun Feb 04, 2018 1:20 am
Hi All,

I need to have a quick to check the values of resistors, so I came up with this little program. A friend saw it an grabbed a copy and said I should share it cause it was quick and easy to use. So here it is as code.

Hope you enjoy and if you find any errors in the calculations let me know.

It was done HW 6.1 but I think it should run on earlier versions, as there is nothing special about the code.

Cheers Leo

The code doesn't work, under MorphOS the variables. Name doesn't work and under Windows the code ask the mui royal.

Here it works, after replacing all "alt-space" (ascii 160) with normal "space" (ascii 32) characters.

Yeah, tabs seem to get broken when you copy code from here. At least under OWB/MorphOS. But once you fix them (for example by using a "replace all" function in some text editor), you get it working.

And programs using MUIRoyale only work under Amiga compatibles naturally

Useful idea for a program, so thanks for sharing!

Hi All,

Sorry about not stating Amiga only, thought it was obvious from the "REQUIRE MUIRoyale"

@ Juan Carlos Never considered SMD's as I have never used them. Will have a look. I intend to add 4 band and 6 band as well.
( I may make a cross platform version using my Simple Gadgets )

@ All Not sure why it changes spaces and tabs during copy and paste. Having the code in some sort of basic format makes it easier to read.
( may have to ask airsoftsoftwair if its a forum thing )

Cheers
Leo
