Get the absolute value of a real or complex number - online calculator
You can get the absolute vale of a real or complex number by the abs command. Input the abs command and a real or complex value like abs -0.24 in the header form and press the enter key, and you get the absolute value. For example, if you input
abs -3
in the search form above, the result (3) appears in the screen. The next example is to calculate the absolute value of a negative floating point number.
abs -0.24
The result is 0.24.
Like Unix/Linux commands, you should separate a command and arguments.
The absolute value of a fraction
The abs command enables you to get the absolute value of a negative fraction like -5/3.
abs -5/3
The result is below.
\[ \frac{5}{3} \]
The absolute value of a complex number
This website supports the arithmetic operations of complex numbers and the abs can take a complex number as argument.
abs 3+4*I
The result is 5. Note that 3+4*I means
\[ 3 + 4 i \]
and an imaginary number i must be written I (capital case). The absolute value of this complex number is the distance of (0, 0) and (3, 4) in the complex plane.
