    Help did not try to look? digits - Alex Krass

    @AlexKrass, So the author does not seem to need it? - s8am
  • @ s8am The author is asked how to set the number (знаков после запятой) . In the help there is an answer, you must write to 1000 digits or 50 digits of to display the answer to a certain sign. Well, we can also assume that the functions of ceiling, floor, round were meant, but this is called rounding and the author has not written anything about this. - Alex Krass

    @AlexKrass, to N digits sets the total number of digits of a number, not the number of decimal places - I'm talking about that. - s8am
  • @s8am would have written right away, but I didn’t notice this behavior, really. Then all the same it is necessary to use mathematical rounding according to the Floor(pi, 1E-2) . - Alex Krass

In order to explicitly specify the required number of characters , you must add the ЧИСЛО_ЗНАКОВ digits of аргумент to the query, for example:

 50 digits of pi

In order to explicitly indicate the required accuracy of rounding , you should wrap the query in the Floor(аргумент, точность) function Floor(аргумент, точность) , for example:

 Floor(pi, 1E-2)
