- complex_number - The complex number whose exponential is to be computed.
c returns the value: 1.46869393991589+2.28735528717884i.
IMEXP(C5) returns the exponential of the complex number contained in C5.
- The exponential of a complex number is defined as follows:
- IMEXP(x+yi) = excos(y) + iexsin(y)
