The x: converts its argument to extended. You are giving it a floating point argument, not an integer, i.e.
180548043269214561950911457875657 1.80548e32 datatype 180548043269214561950911457875657 floating To use this value as an extended integer you need the 'x' suffix. 180548043269214561950911457875657x 180548043269214561950911457875657 If you have the value as a string, then append 'x' and evaluate it: A=: '180548043269214561950911457875657' ".
