$sformatf() and $format()

What is the difference between $sformatf() and $sformat() and $psprintf()?

Please explain.

In reply to ViKKi:

You can find this information in the IEEE 1800-2017 SystemVerilog LRM.

In reply to ViKKi:

$psprintf is not in the LRM. It is a legacy name and equivalent to $sformatf.
