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.

PreviousPrime syntax

  %value = number: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}
