    Funktionsnavn:

    LOFT.MATEMATIK

    Kategori:

    Matematisk

    Resume:

    Afrunder et tal til det nærmeste multiplum af en signifikant værdi.

    Syntaks:

    LOFT.MATEMATIK(Number [; Significance [; Mode]])

    Returnerer:

    Returnerer en heltalsværdi.

    Argumenter:

    Tal er det reelle tal, som skal afrundes, eller en reference til en celle, der indeholder tallet.

    Signifikans (valgfri) er den reelle værdi, eller en reference til en celle, der indeholder den værdi, som tallet skal afrundes til et multiplum af. Standardværdien er +1 eller -1 afhængigt af tallets fortegn.

    Tilstand (valgfri) er et tal, eller en reference til en celle, der indeholder et tal. Funktionen bruger kun tilstand, hvis både tallet og den signifikante værdi er negativ. Så hvis tilstand er givet og ikke lig med nul, rundes tallene ned (væk fra nul). Hvis tilstand er lig med nul eller ikke givet, rundes negative tal op (imod nul).

    • If any argument is non-numeric, then LOFT.MATEMATIK reports a #VÆRDI! error.
    • If either Number or Significance is equal to 0, then LOFT.MATEMATIK returns 0.

    Advarsel:
    Denne funktion eksisterer af hensyn til interoperabilitet med Microsoft Excel 2013 eller neyere.

    • With Significance set to -1 or +1, or defaulted to 1, and Mode set or defaulted to 0 or FALSK, LOFT.MATEMATIK provides functionality that implements the standard mathematical definition of a ceiling value.
    • LOFT.MATEMATIK is similar to the AFRUND.LOFT function, the difference between the two lying in the interpretation of the Significance argument. The AFRUND.LOFT function requires the Significance and Number arguments to have the same sign, whereas for LOFT.MATEMATIK the sign of the Significance argument is ignored.


    General information about Calc's ceiling functions

    Note pin.svg

    Bemærk:
    For convenience, the information in this subsection is repeated on all pages describing Calc's ceiling functions.

    General introductory information about ceiling functions can be found at Wikipedia's Floor and ceiling functions page.

    Calc provides five functions that can be used to calculate the ceiling value of a number, and these are:

    The most important of these for many users will be the AFRUND.LOFT function, which implements the requirements laid out in Section 6.17.1 of ODF 1.2, Part 2.

    Calc provides the LOFT.MATEMATIK, LOFT.PRECISE, and ISO.LOFT functions to increase interoperability with Microsoft Excel, which provides three similar functions with the same names. Calc's LOFT.PRECISE and ISO.LOFT perform identical functions.

    Microsoft Excel's AFRUND.LOFT function accepts two arguments and so is not compliant with ODF 1.2. This difference in behaviour could lead to interoperability problems but these are avoided through the provision of the LOFT.XCL function, as follows:

    • When Calc saves a spreadsheet to Excel 2007-365 (*.xlsx) format, any call to Calc's AFRUND.LOFT function is converted to a call to Excel's LOFT.MATEMATIK function, and any call to Calc's LOFT.XCL function is converted to a call to Excel's AFRUND.LOFT function.
    • When Calc opens a spreadsheet in Excel 2007-365 (*.xlsx) format, any call to Excel's AFRUND.LOFT function is converted to a call to Calc's LOFT.XCL function.

    Eksempler:

    Formula Description Returns
    =LOFT.MATEMATIK(11,5) Significance defaults to 1 and Mode defaults to 0. The function rounds up 11.5 to the nearest integer multiple of 1. 12
    =LOFT.MATEMATIK(−11,5) Significance defaults to 1 and Mode defaults to 0. The function rounds up -11.5 to the nearest integer multiple of 1. −11
    =LOFT.MATEMATIK(7; 2,3) Mode defaults to 0. The function rounds up 7 to the nearest integer multiple of 2.3. 9,2
    =LOFT.MATEMATIK(−7; −2,3) Mode defaults to 0. The function rounds up -7 to the nearest integer multiple of 2.3 (the sign of the significance value is ignored). −6,9
    =LOFT.MATEMATIK(D1; D2; D3) where cells D1, D2, and D3 contain the numbers 10, 3, and 1 respectively. The function rounds up the value 10 to the nearest integer multiple of 3. The value of Mode is not significant for a positive number. 12
    =LOFT.MATEMATIK(−10; −3; 0) With Mode set to 0, the function rounds up the value -10 to the nearest integer multiple of 3 (the sign of the significance value is ignored). −9
    =LOFT.MATEMATIK(−10; −3; 7,6) With Mode set to a non-zero value, the function rounds down the value of -10 to the nearest integer multiple of 3 (the sign of the significance value is ignored). −12
    =LOFT.MATEMATIK(−3,6; ; SAND()) Significance defaults to 1. With Mode set to a non-zero value, the function rounds down the value of -3.6 to the nearest integer multiple of 1. −4
