How to use the IMREAL function

The image above demonstrates a formula in cell D3 that calculates the real coefficient of a complex number specified in cell B3.

Formula in cell D3:

=IMREAL(B3)

3.1 Explaining formula

Step 1 - Populate arguments

IMREAL(inumber)

becomes

IMREAL(B3)

Step 2 - Evaluate the IMREAL function

IMREAL(B3)

becomes

IMREAL("1+2i")

and returns
