<> | not equal to | |

= | equal to | |

in | is the first value in the list of other parameters e.g.: in(1, 3,4,5,6,7,8,1,2,9) returns 7, as the first value is found in the 7th position in the list of other parameters, if not found 0 is returned | |

logN | logarithm base x of y | |

power | power: x^y | |

pow | power: x^y | |

intpower | power: x^y | |

radtodeg | conversion of rad to degrees | |

textvalue | returns numeric value of text variable (e.g.: tekst value contains '3456' then that is returned as a value, if the text variable contains '3456T' system missing is returned | |

label | Is the first parameter true return the second, third true then return 4th, Nth (oneven) is true return Nth even parameter | |

notmissing | return the first value that is not sysmissing from the array of parameters | |

avg | returns the average of the passed values | |

IsNull | Equals spps null system missing | |
