This is a true squareroot callable common event. Of course since RM doesn't support decimals the returned squareroot cannot be a decimal, but the system does round properly as if there were decimals. Eg. Root6 = 2.449 thus it rounds down to 2, while Root7 = 2.645 thus it rounds up to 3.



To use:
Simply copy the common event in this template to your game. Then when you want a square root set Variable #100 to the number you want to root, then call the common event you copied. After the call Variable #100 will be the square root! (See the tree stump event in the middle of the template's map for an example) By default the system uses variables 97-100. This can be changed in a minute or two by changing all the variable references in the common event to other ones. Just make sure they all match up.
(Note: There is an upper limit on square roots. Not because the system is limited, but because I thought nobody would want to square root that high anyway, so I put it there to prevent infinite loops that might happen for some reason. See the bottom of the common event to set this higher if you need it higher.)

Enjoy!
