Information N Int Value Any The N() function converts a value to a number. If value is or refers to a number, this function returns the number. If value is True, this function returns 1. If a value is a date, this function returns the serial number of that date. Anything else will cause the function to return 0. N(value) N(3.14) returns 3.14 N("7") returns 0 (because "7" is text) INFO String Type of information String The INFO() function returns information about the current operating environment. Parameter type specifies what type of information you want to return. It is one of the following: "directory" returns the path of the current directory, "numfile" returns the number of active documents, "release" returns the version of KSpread as text, "recalc" returns the current recalculation mode: "Automatic" or "Manual", "system" returns the name of the operating environment, "osversion" returns the current operating system. INFO(type) ISLOGICAL Boolean Any value Any The ISLOGICAL() function returns True if the parameter is a boolean value. Otherwise it returns False. ISLOGICAL(x) ISLOGICAL(A1>A2) returns True ISLOGICAL(12) returns False ISBLANK Boolean Any value Any The ISBLANK() function returns True if the parameter is empty. Otherwise it returns False. ISBLANK(x) ISBLANK(A1) returns True if A1 is empty ISBLANK(A1) returns False if A1 holds a value ISNUMBER Boolean Any value Any The ISNUMBER() function returns True if the parameter is a numerical value. Otherwise it returns False. ISNUMBER(x) ISNUMBER(12) returns True ISNUMBER(hello) returns False ISTIME Boolean Any value Any The ISTIME() function returns True if the parameter is a time value. Otherwise it returns False. ISTIME(x) ISTIME("12:05") returns True ISTIME("hello") returns False ISDATE Boolean Any value Any The ISDATE() function returns True if the parameter is a date value. Otherwise it returns False ISDATE(x) ISDATE("2000-2-2") returns True ISDATE("hello") returns False ISREF Boolean Any value Any The ISREF() function returns True if the parameter refers to a reference. Otherwise it returns False ISREF(x) ISREF(A12) returns true ISREF("hello") returns false ISTEXT Boolean Any value Any The ISTEXT() function returns True if the parameter is a string. Otherwise it returns False ISTEXT(x) ISTEXT(12) returns False ISTEXT("hello") returns True ISNONTEXT Boolean Any value Any The ISNONTEXT() function returns True if the parameter is not a string. Otherwise it returns False ISNONTEXT(x) ISNONTEXT(12) returns True ISNONTEXT("hello") returns False ISODD Boolean Any value Any The ISODD() function returns True if the number is odd. Otherwise returns False. ISODD(x) ISODD(12) returns False ISODD(-7) returns True ISEVEN Boolean Any value Any The ISEVEN() function returns True if the number is even. Otherwise returns False. ISEVEN(x) ISEVEN(12) returns True ISEVEN(-7) returns False TYPE Int Any value Any The TYPE() function returns 1 if the value is a number, 2 if it is text, 4 if the value is a logical value, 16 if it is an error value or 64 if the value is an array. If the cell the value represents contains a formula you get its return type. TYPE(x) TYPE(A1) returns 2, if A1 contains "Text" TYPE(-7) returns 1 TYPE(A2) returns 1, if A2 contains "=CURRENTDATE()" FILENAME String Returns the current filename. If the current document is not saved, an empty string is returned. FILENAME()
