isfloat
Determine if input is floating-point array
Syntax
Description
Examples
Determine Whether Numbers Are Floating-Point Type
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
A
— Input array
scalar | vector | matrix | multidimensional array
Input array, specified as a scalar, vector, matrix, or multidimensional array.
Floating-point types in MATLAB® include single
and double
(and
subclasses of single
and double
).
