PreviousPrime (Float function)

Find greatest prime smaller than this number (Float class)

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

Syntax

%number = float:PreviousPrime

Syntax terms

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

Usage notes

• The method object value 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 method object value, even if the method object value is prime.
• PreviousPrime is available as of "Sirius Mods" Version 7.3.

Examples

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

   printText {~} = {2.8:previousPrime}
