Find greatest prime smaller than this number (Float class)


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

The PreviousPrime function is available as of version 7.3 of the Sirius Mods.

Syntax

%number = float:PreviousPrime

Syntax terms

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

Usage notes

  • The method object value is initially rounded to the nearest integer before the preceding prime is determined.
  • If number rounds to 2 or less or is greater than 231-1, the request is cancelled.
  • PreviousPrime always returns a value lower than the method object value, even if the method object value is prime.

Examples

The following statement returns "2.8:previousPrime = 2".

PrintText {~} = {2.8:previousPrime}
