Calculates e to the power of a given complex number. e is a mathematical constant known as Euler's number, which has a value of approximately 2.71828.
Returns a text string giving the complex number that results from raising e to the power of the complex number passed as argument.
ComplexNumber is a string (in quotation marks) representing a complex number in the form a+bi or a+bj, or a reference to a cell containing that string, which is the power to which e is to be raised. a and b are real numbers.
- If ComplexNumber does not have an imaginary part (b equal to 0), the real part can be passed to IMEXP as a number rather than a string.
- If ComplexNumber is not a valid complex number, IMEXP reports an invalid argument error (Err:502).
Details specific to IMEXP function
For a complex number of the form a+bi, IMEXP implements the following equation:
This equation is based on Euler's formula – more information can be found on Wikipedia’s Euler's formula page.
General information about Calc's handling of complex numbers
- A complex number is a number that can be expressed in the form a+bi, where a and b are real numbers and i is a symbol for the imaginary unit, such that i2=−1. a is known as the real part of the complex number and b is known as its imaginary part.
- In some disciplines using i to indicate the imaginary unit may be undesirable and, in such cases, the symbol j may be used instead. The functions provided by Calc to process complex numbers can use either i or j.
- For additional general background information, visit Wikipedia’s Complex number page.
- Within Calc, a complex number is represented as a string expression of the form "a+bi" or "a+bj", where a and b are real numbers. If the complex number happens to be a real number (b=0), then it can be represented as either a string expression or a numeric value. Complex number string expressions should not contain any space characters. Examples of valid Calc complex numbers include "2", -6, "2+3i", "3j", "12.34+56.78i", and "1e+23-1e-22j". Calc would not recognize the strings "1+j2", "i+1", and "i+j" as valid complex numbers.
- The representation of the complex numbers in strings can have up to 15 significant digits and scientific style is automatically used if needed (visit Wikipedia’s Scientific notation page for more information). The decimal delimiter in complex number string expressions is always a dot, irrespective of locale setting.
