a simple help on syntax

[giorgino]

an easy question...
working with floating number, I need to pass integer value to this

NEXTION,page2.n0.val=6

and I obtain 6

and when I have 2 integer:

NEXTION,page2.n0.val=6+2

obatain 8

then I write

NEXTION,page2.n0.val=7.2+2

and doesn't work

...I know, it' s so easy...

I guess you're generating these in rules?

If so, then you can use the let command to compute an intermediate value and store it in a variable.

Code: Select all

let,1,7.2+2 // Store in variable #1
NEXTION,page2.n0.val=[var#1]

[giorgino]

ah , ok
so, no direct in the

NEXTION,page2.n0.val=7.2+2

?

The inline-parsing isn't working like that.
Only with the '=' on the first position when parsing numerical values, the parser will try to evaluate the formula.
However this may give some unexpected results, so best to use "let" to evaluate calculations.

ok, good!
now, I need to send integer, so my syntax become:

let,1,round(([MQTbox#dm_vol]-9000)*0.03) // Store in variable #1 l'angolo di riferimento dei volt batteria (dm_volt)
NEXTION,page1.z1.val=[var#1]

but if I need to truncate my floating 12.347 to 12.34 can I use something like ROUND(x,2) ?

You'll need a transformation, as documented here
So your case could be like

Code: Select all

let,1,([MQTbox#dm_vol]-9000)*0.03 // Store in variable #1 l'angolo di riferimento dei volt batteria (dm_volt)
NEXTION,page1.z1.val=[var#1#d1.2]

The 'd' is a Decimals transformation, with spaces prefix if needed ('D' is with zeros prefixed)
the '1' is a minimum of 1 digits before the decimal point (you can set to 0 if desired)
the '.2' is having 2 decimals after the decimal point, value is rounded.

The value is stored in a floating point format, so no information about the number of decimals is stored, that's to be specified when 'presenting' the value, hence the formatting and justification options are included in the variable retrieval.

GREAT!!
