Complex number functions

Complex number functions provide arithmetic, mathematical and trigonometrical functions for use with complex numbers, i.e. numbers which have both real and imaginary components.

In Fireworkz complex numbers must be expressed as

• a 1×2 range of cells (or array);
• composed using the C_COMPLEX function;
• as an OpenDocument / Microsoft Excel-style complex number string.

• C_ADD( complex_addend_1, complex_addend_2 )
• C_COMPLEX( real part {, imaginary part} ) also
  C_COMPLEX( real part, imaginary part, suffix )
• C_CONJUGATE( complex_number )
• C_DIV( complex_dividend, complex_divisor )
• C_EXP( complex_number )
• C_IMAGINARY( complex_number )
• C_LN( complex_number )
• C_MUL( complex_multiplicand_1, complex_multiplicand_2 )
