These examples show the values isfloat returns when passed specific types:

% pi returns a floating-point value
isfloat(pi)
ans = logical
   1


% Complex numbers are floating-point values
isfloat(3+7i)
ans = logical
   1


% Single-precision numbers are floating-point values
isfloat(realmax('single'))
ans = logical
   1


% isfloat returns a logical value
isfloat(isfloat(pi))
ans = logical
   0

Input Arguments
