function [varargout] = isfloat(varargin)
%ISFLOAT True for floating point arrays, both single and double.
%   ISFLOAT(A) returns true if A is a floating point array and false otherwise.
%
%   Single and double are the only floating point data types in MATLAB.
%
%   Example:
%      isfloat(single(pi))
%      returns true since single is floating point data type while
%      isfloat(int8(3))
%      returns false since int8 is not a floating point data type.
%
%   See also ISA, DOUBLE, SINGLE, ISNUMERIC, ISINTEGER.
