The PreviousPrime intrinsic function returns the prime number that immediately precedes the method object value.


%number = float:PreviousPrime

Syntax terms

%number A numeric variable to receive the method result.
float A Float value.

Usage notes

  • The method object value, float, is initially rounded to the nearest integer before the preceding prime is determined.
  • If float rounds to 2 or less or is greater than 231-1, the request is cancelled.
  • PreviousPrime always returns a value lower than the current float value, even if float is currently prime.
  • PreviousPrime is available as of Sirius Mods Version 7.3.


The following statement returns 2.8:previousPrime = 2.

printText {~} = {2.8:previousPrime}
