How does the "Trim" text block work?

so im trying to make a shockwave procedure that utilizes falling blocks and so the coordinates need to be exact so the block fall back into place right and I'm using "get player x/z position" and of course that has a lot of numbers after the decimal place and I tried using the "format number" block but that would just end up rounding the number which isn't what I want.

I need to cut off everything on the right side of the decimal, not round the number itself.

so I thought converting the number to text and then using the trim block would maybe work but I cant seem to figure out how to use the time block.

anyone here know how it works?
