The
IMABS() function calculates absolute
value of a complex number.
- The syntax for the function
is IMABS(inumber).
The
argument "inumber" is
a complex number of the form (a+bi) where
a and b are real number coeffcients.The
IMABS function returns the absolute value
(also known as modulus) of a complex number.
For example: IMSUB("4+3i") =
5. The function squares the real
and imaginary components independently
adds them and then returns square root
in the form of a real number. As (4+3i)
= SQRT[(8)^2+(3i)^2] = SQRT[(16)+(9)]
= SQRT[25]= 5. To
learn more about real, imaginary and complex
numbers in mathematics see [The Mathematics
of Complex Numbers].
Note: To
convert real and imaginary numbers into
a complex number use the COMPLEX() function.

Note: The"i" suffux
is commonly used in mathematics whereas
the "j" notation
is a more commonly used notation in electronic
fields. However both are used to represent
the vertical vector component of a complex
number when written in rectangular coordinates
or when graphed in complex space.
