First, the default forced conversion, floating or double conversion to plastic.
Second, please reread your program block diagram to see if there is a red triangle symbol at the connection point. If there is, it means a cast.
In LabVIEW, you can enter a numerical value in the program block diagram, and then right-click to select it as a fixed point (FXP), the numerical border and connecting line will turn gray, and right-click the attribute and data type to deselect the matching input data. Set the position of the decimal point below. The first number is the total number of binary digits used, and the second number is the number of digits occupied by the integer part. Floating-point type is so common, needless to say. Double precision (DBL) is usually used by default in LabVIEW.
