SYNOPSIS
    nextprime(n [,err])

TYPES
    n		real
    err		integer

    return	positive integer or err

DESCRIPTION
    If n is an integer less than 2^32, nextprime(n) returns the
    first prime greater than n.

    If n <= 2 or >= 2^32 or n is fractional, prevprime(n, err)
    returns the value of err.

    Other cases cause a runtime error.
