Values sent on a wire

Note: These block outputs and inputs are also called output ports and input ports. See also Adding a wire between two blocks.

Wires allow blocks to pass signals and values between blocks. The value sent on a wire is one of the following types, according to the block output from which it is connected:

Type	Description
boolean	A true or false value. A Boolean value stays true or false until changed.
float	A numeric value, which can be fractional (and processed using fixed precision). A float value maintains its current value until changed.
string	A textual value. A string value maintains its current value until changed.
pulse	A signal of a point in time. Pulses are only active momentarily. Unlike the above types, they only represent a single instance in time. See also The pulse type.
any	A value that may be any of the above types. See also The any type.

The type of a wire depends on the output to which it is connected. This can be viewed in the block reference. Similarly, the type (or supported types) of a block's input can be viewed in the block reference.
