Let i be an imaginary unit.
Let x , y be real numbers, z be a complex
|COMPLEX(x , y)||Complex number x + y i|
|RE(z)||The real part of z, i.e., RE(x + y i)= x|
|IM(z)||The imaginary part of z, i.e., IM(x + y i)= y|
|CONJ(z)||The conjugate of z, i.e., CONJ(x + y i)= x - y i|
|ARG(z)||The argument of z, i.e., arg z . The result depends on the angle option.|
In case of angle radians, the result is greater than -π and not greater than π.
In case of angle degrees, the result is greater than -180° and not greater than 180°,
|ABS(z)||The absolute value of z, |z||
|SQR(z)||The square root of z,
the argument of which is greater than that -π and not greater than π. |
For example, SQR(-1)=i.
|EXP(z)||The exponential function.|
|LOG(z)||The natural logarithm of z, i.e., the complex number with real part log|z|, imaginary part arg z, where the unit is radians and is greater than π and not greater than π|
<Note> EXP(z) and LOG(z) are not affected by the angle option.
