Ceil() function does not work correctly:

ceil(1)   -->returns 1
ceil(1.0) -->returns 2 (Error)

Same for any N.0 float. Seems to work correctly in other circumstances.

LUA math.ceil(1.0) correctly returns 1 and can therefore be used as an alternative in the meantime.

Tested with version 0.1.0e on Windows 10

(I already posted this in the 'Picotron bugs' thread, but including it here with a proper 'Bugs' tag as I couldn't work out how to add a tag to the other post)
