Syntax |
IsPrime(N:INT):BOOL |
Summary |
prime integer test |
Description |
This function determines whether a small integer is prime. The range of permitted values for N is the same the range of permitted values for the NextPrime function: on most platforms N < 45000 should work fine, on some platforms considerably larger values will work. For N greater than the limit an error is raised. |
Example |
IsPrime(32003); TRUE ------------------------------- IsPrime(10^100); ERROR: IsPrime: number too large CONTEXT: Return(Error("IsPrime: number too large")) ------------------------------- |
