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

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

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}
