Delphi-Quellcode:

const   { Ranges of the IEEE floating point types, including denormals }
  MinSingle   =  1.5e-45;
  MaxSingle   =  3.4e+38;
  MinDouble   =  5.0e-324;
  MaxDouble   =  1.7e+308;
  MinExtended =  3.4e-4932;
  MaxExtended =  1.1e+4932;
  MinComp     = -9.223372036854775807e+18;
  MaxComp     =  9.223372036854775807e+18;

  { The following constants should not be used for comparison, only
    assignments. For comparison please use the IsNan and IsInfinity functions
    provided below. }
  NaN         =  0.0 / 0.0;
  Infinity    =  1.0 / 0.0;
  NegInfinity = -1.0 / 0.0;

Wie gesgt, MaxSingle und -MaxSingle .
