Creates a number from the component bytes or words.
The connector pane displays the default data types for this polymorphic function.

Inputs/Outputs
hi
—
hi can be an 8-, 16-, or 32-bit number or an array or cluster of that representation.
lo
—
lo can be an 8-, 16-, or 32-bit number or an array or cluster of that representation.
(hi.lo)
—
(hi.lo) is an integer twice the width of hi and lo. (hi.lo) is a 16-, 32-, or 64-bit unsigned integer or an array or cluster of those representations. If hi and lo are of different widths, (hi.lo) is twice the width of the widest number. |
FPGA Module Details
The following details apply when you use this object in an FPGA VI.
Note The following details are subject to change with each version of the LabVIEW FPGA Module.
| Single-Cycle Timed Loop | Supported. |
| Usage | N/A |
| Timing | This function requires no clock cycles to execute because it does not include an internal register. |
| Resources | This function consumes no FPGA resources because it is purely a wiring operation. |
