List of Calc Complex Number functions
Complex numbers are a mathematical concept, and have a real and an imaginary part. In Calc, they are represented by text, for example as a + bi or a + bj. The following functions create or manipulate that text.
The representation of the numbers in the text can have up to 15 significant digits. Scientific style is automatically used if needed. The decimal delimiter is always a dot, local style of numbers is not possible inside the text. The text may not contain any blanks.
| COMPLEX | Returns a complex number, given real and imaginary parts. |
| IMABS | Returns the absolute value of a complex number. |
| IMAGINARY | Returns the imaginary part of a complex number. |
| IMARGUMENT | Returns the argument of a complex number. |
| IMCONJUGATE | Returns the complex conjugate of a complex number. |
| IMCOS | Returns the cosine of a complex number. |
| IMDIV | Returns the result of dividing one complex number by another. |
| IMEXP | Returns e to the power of a complex number. |
| IMLN | Returns the natural logarithm of a complex number. |
| IMLOG10 | Returns the base-10 logarithm of a complex number. |
| IMLOG2 | Returns the base-2 logarithm of a complex number. |
| IMPOWER | Returns a complex number raised to a power. |
| IMPRODUCT | Returns the product of complex numbers. |
| IMREAL | Returns the real part of a complex number. |
