Meanwhile, in the real world, truncation of a number or a series means reducing its precision. Of a floating point number, it’s removing the fractional part. Exactly the use you want to suppress. Why in the world do you insist that it must be redefined to be something else? Must Swift be incomprehensible to the uninitiated?
