I have been trying to get some equations to work, using regular normal expressions.
fuelG.pic=46 - ((20/100)*fuel_var.val)
This should change the image displayed in the fuelG image box to the correct image in a 20 image sequence. fuel_var holds a number that was passed to it from the main MCU between 0 and 100...
The maths is sound and is a normal style of expression. But the IDE wont compile it.
Removing parenthesis obviously brakes the formula and would result is incorrect numbers being calculated.
Also you will notice 20/100 is 0.2
This is another issue the ide doesnt like handling decimals. In most normal situations a decimal would be rounded to the nearest whole number. But the compiler throws another error.
Nextion Instruction Set states - complex expressions not supported
Order of operations requires complex expressions
Nextion is integer based without floating point
30/100 is 0
250/100 is 2
99 /25 is 3
Parsing is occurring on each operator right to left.
will parse as
The proper way to approach such is
This is not a Bug but the expected behaviour on embedded integer based level
