RealAbs

RealAbs[x]

gives the absolute value of the real number x.

Details

  • RealAbs is also known as modulus.
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • RealAbs[x] is effectively equivalent to Piecewise[{{x,x>=0}},-x].
  • RealAbs is continuous and differentiable everywhere except at the origin.
  • RealAbs[x] is left unevaluated if x is not a numeric quantity.
  • RealAbs automatically threads over lists.
