abs(x)
Absolute value.
Declaration
Syntax
Arguments
x
the input value, can be integer, real, or complex.
Return values
The return value is of type and kind same as of x
. For complex input value,
return value is real.
Description
abs(x) calculates and returns absolute value of x
. Result is calculated
using mathematical formula:
\(|x|\)
If x
is complex, the result is calculated using mathematical formula:
\(\sqrt{(x^2 + y^2)}\)
Types
Supported argument types are real and integer.
