Displaying decimal values

Anthony240

I have been working with the basic stamp trying to measure salinity.· I have finally got the circuit to measure changes in resistance when I place my probes in different salt water solutions.· I now have ran into another problem.· I cannot display the numbers in decimal values.· Anything below 1 shows up as 0.· I am needing to display salinity as specific gravity and those numbers are around 1.023-1.028

thanks

What is happening is the basic stamp works with whole numbers. So when you get a reading of 1.023 the stamp will round that to 1. you should be able to chang your circuit so your readings are whole numbers. Like a reading of 1023. then change that to a decimal
manualy with the debug camand.

here is a peace of code to give you an idea:

number CON 1023

DO
DEBUG HOME, CR, DEC1 number/1000, ".", DEC3 number - 1000

LOOP

try it. it works

You don't even need the "- 1000" at the end; using DEC3 truncates to the lowest three digits.
