The IMEXP function returns the exponential of a complex number in x + yi or x + yj text format
Syntax:= IMEXP(inumber)
The IMEXP function syntax has the following arguments:
 Inumber: Required. A complex number for which you want the exponential
Example: Let’s look at some Excel IMEXP function examples and explore how to use the IMEXP function as a worksheet function in Microsoft Excel:
Syntax: =IMEXP(A2)
Result:
Based on the Excel spreadsheet above, the following IMEXP examples would return:
Syntax: =IMEXP(A3)
Result: 3.07493232063936+6.71884969742825i
