Finally! I have completed my first compound! It's a bit rough, and maybe it's not very efficient, but it works.
It's basically similar to the Python round() function, except that it outputs a string:
0 => "0.00"
15.5 => "15.50"
-0.3876 => "-0.39"
number: plugin some number.
has_decimal: decide how many decimal places to keep. 0: do not keep decimals; 1: keep one decimal place; 2: keep two decimal places. and so on.
is_round: whether to round.
I hope that in the future Bifrost's round_to_nearest and number_to_string will replace this compound because these two nodes should be handling these basic functions.
