Assuming you are asking, the answer is that it depends on the node, but built-in objects will typically generate code that doesn't take extra code for a single integer and float being mixed together. As I mentioned, arrays are different. There aren't instructions to deal with an array at a time, and it normally takes another buffer. A coercion dot generates the same code as an equivalent conversion block. The real time they are useful is to do conversions at a different point in the diagram. For example, if you are producing integers in a loop, building an arry, then later the array gets converted into an array of double, using either conversion or coercion dots, it will use memory for the array of ints, array of doubles, and some small storage for the scalars in the loop. If you instead do the conversion inside the loop, the integer array never gets made, and the total storage is for one array of double, and then an additional scalar inside the loop. Greg McKaskle

Thanks Greg. Here i want to add something. If i connect a integer to float terminal LabVIEW allocates the memory twice a times unless if i do a proper conversion. As per your s/n it should not allocate a memory for array conversion too. Pls Let me know if it is wrong.

> What LabVIEW does internally while coercion dots appears in block > diagram? The coercion dot indicates a datatype change is taking place. In some cases, it takes little or no time. A coercion from an unsigned to a signed integer is essentially free since the same amount of code will be generated either way, but the condition flags will look different. For integer to floats, the node will often just load one integer into a floating point register and no additional storage is needed. Other times, like with an array, the dot may mean that a new storage buffer is needed and the dot is equivalent to a coversion bullet. Does this answer your question? Greg McKaskle
