ST Editor Tooltips #2412

i Guess i found an Error in ST Editor:

F_RAW_TO_PHYS := LINT_TO_REAL(UDINT_TO_LINT(u32Raw) + DINT_TO_LINT(stObj.i32Offset)) * stObj.r32Scale;

IF i write:

F_RAW_TO_PHYS := DINT_TO_REAL(UDINT_TO_DINT(u32Raw) + stObj.i32Offset) * stObj.r32Scale;

at the Stage:
UDINT_TO_DINT(u32Raw)
value can get negative.

so the Solution in the First line is the safe one, right ?

but ST Editor says "unneccessary Conversion" ..
if i accept both, i end with an Error:

F_RAW_TO_PHYS_LREAL := UDINT_TO_LREAL(u32Raw + stObj.i32Offset) * stObj.r32Scale;
Operator + is not applicable for types UDINT and DINT
