AK3(CPLX)2(Abs)
!*( ( )d+e1(
i)!/( ) )w
(Calculation of absolute value)
AK3(CPLX)3(Arg)
!*( ( )d+e1(
i)!/( ) )w
(Calculation of argument)
• The result of the argument calculation differs in accordance with the current angle unit
setting (degrees, radians, grads).
k Conjugate Complex Numbers [OPTN]-[CPLX]-[Conj]
A complex number of the form
a + bi becomes a conjugate complex number of the form
a – bi.
Example To calculate the conjugate complex number for the complex number
2 + 4
i
AK3(CPLX)4(Conj)
!*( ( )c+e1(
i)!/( ) )w
k Extraction of Real and Imaginary Parts [OPTN]-[CPLX]-[ReP]/[lmP]
