Hi, I sent you question on email.

By the way, there is no command PrintFloat variable. In usual connection there is for HD44780. But in combination with I2C I can not print float variable on the LCD screen. Can any resolve this or may I open special topic for this question?

Hi

You could use the FloatToString$ in a calculation then print the result. I think Ben and Medelec have posted much on this subject so a quick search might be of help.

Below x= the resulting String / y = floating point variable / z = how many decimal points to include


Hope this helps
