Microsoft Excel wrongly assumes year 1900 to be a leap year and considers the inexistent day of 1900-02-29 as valid in date calculations. Dates prior to 1900-03-01 are therefore different in Excel and Calc.

复数 是一个字符串表达式, 形如「a+bi」或「a+bj」, 其中 a 和 b 为数字。

如果「复数」实际上是一个实数 (b=0), 那么它既可以是一个字符串表达式, 也可以是一个数字值。

该函数始终返回一个表示复数的字符串。

如果结果是一个复数, 其一部分 (a or b) 等于零, 则不显示该部分。

虚部等于零, 因此它不会显示在结果中。

结果以字符串格式显示, 并将字符「i」或「j」作为虚部的单位。

String 1 [; String 2 [; … [; String 255]]]

String 1; String 2; … ; String 255 are strings, references to cells or to cell ranges of strings.

Integer 1 [; Integer 2 [; … [; Integer 255]]]

Integer 1; Integer 2; … ; Integer 255 are integers, references to cells or to cell ranges of integers.

Number 1 [; Number 2 [; … [; Number 254]]]

Number 1; Number 2; … ; Number 254 are numbers, references to cells or to cell ranges of numbers.

Number 1 [; Number 2 [; … [; Number 255]]]

Number 1; Number 2; … ; Number 255 are numbers, references to cells or to cell ranges of numbers.

Logical 1 [; Logical 2 [; … [; Logical 255]]]

Logical 1; Logical 2; … ; Logical 255 are boolean values, references to cells or to cell ranges of logical values.

Complex 1 [; Complex 2 [; … [; Complex 255]]]

Complex 1; Complex 2; … ; Complex 255 are complex numbers, references to cells or to cell ranges of complex numbers. Complex numbers are entered in the form "x+yi" or "x+yj".

Reference 1 [; Reference 2 [; … [; Reference 255]]]

Reference 1; Reference 2; … ; Reference 255 are references to cells.

This function is always recalculated whenever a recalculation occurs.

The function is always case insensitive, independent from the setting of Case sensitive checkbox in LibreOffice - Preferences Tools - Options - LibreOffice Calc - Calculate. You can however, use the mode modifier (?-i) in regular expressions to force search for a case-sensitive match.
