Rescale

Rescale[x,{min,max}]
gives x rescaled to run from 0 to 1 over the range min to max.

Rescale[x,{min,max},{ymin,ymax}]
gives x rescaled to run from ymin to ymax over the range min to max.

Rescale[list]
rescales each element of list to run from 0 to 1 over the range Min[list] to Max[list].

DetailsDetails

  • Rescale[x,{min,max}] is effectively equivalent to (x-min)/(max-min).
  • For exact numeric quantities, Rescale internally uses numerical approximations to establish its result. This process can be affected by the setting of the global variable $MaxExtraPrecision.
  • Rescale works with complex numbers and symbolic quantities.
