abs
Computes the absolute value of an expression.
Nerdamer simplifies absolute values when sign information is available from numbers, algebraic structure, or assumptions. Even powers are recognized as non-negative, while genuinely sign-unknown expressions remain wrapped in abs.
For complex inputs, absolute value is the complex modulus.
Examples
These examples use Nerdamer Notation.
Take the absolute value of a negative number.
abs(-5) // → 5
Recognize an even power as non-negative.
abs(x^2) // → x^2
Preserve an unknown sign symbolically.
