Re - gets the real component

  • Gets the real component of a complex number

  • Given a complex number a + bi, the Re function returns the value of a

The real part of a complex number is the purely real part of the number. The real part of the complex number 2 - 5i is therefore 2. We also write Re (2 - 5i) = 2.
  • Re (x)
  • Re(12+2i)=12
