This is a web-version of a tutorial chapter embedded right into the XOD IDE.
To get a better learning experience we recommend to install the
or start the
, and you’ll see the same tutorial there.
XOD uses fractional numbers (also known as floats) extensively. For example, the
LUM pin on the
led node can take values from 0 to 1. 0 means absolute
minimum of LED brightness. Basically, it means that LED is off. 1 means full
brightness. You can control LED brightness by setting fractional values on
The circuit is the same as for the previous lesson.

Use Inspector to enter a value with floating point. The following notations are
- .4 (same as 0.4)
- 4e-6 (scientific, 4×10-6 = 0.000004)
