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?
