COMPLEX(RN,IN,SF)

• 'RN' is the real number.
• 'IN' is the imaginary number.
• 'SF' is the suffix for the imaginary number.

Description

• COMPLEX function converts the real and imaginary coefficients into a complex number.
• A complex number is a number is in the form $z=a+bi$, where a and b are real numbers and $i$ is the imaginary unit. Where $i={\sqrt {-1}}$
• In $COMPLEX(RN,IN,SF)$, here RN is the real part of a complex number,IN is the imaginary part of a complex number and SF is the imaginary unit of a complex number like $i$ or $j$.
• To mention $i$ and $j$, we must use the lower case only
• In a complex number $z$ real part is denoted by $Re(z)$ & imaginary part is denoted by $Im(z)$.
• COMPLEX returns the error value, when RN and IN are non-numeric.
• Suffix 'SF' should be either $i$ or $j$, otherwise it shows error value.
• A Complex number whose real part is zero is said to be purely imaginary.
• A Complex number whose imaginary part is zero is a real number. In that cases we have to assign '0' for that part.

• • $=COMPLEX(5,2)$ gives $5+2i$
  • Failed to parse (syntax error): {\displaystyle =COMPLEX(5,2,"j")} gives $5+2j$
