- We can use COMPLEX function to convert real and imaginary number in to a complex number.
Examples
- IMLN("3-2i")=1.28247467873077-0.588002603547568i
- IMLN("6+7i")=2.22132562824516+0.862170054667226i
- IMLN("4")=1.38629436111989 But calci is not considering the zero value of imaginary value of z.
- IMLN("10i")=2.30258509299405+1.5707963267949i
