Determine if input is floating-point array

Syntax

Description

`tf` = isfloat([A](#mw%5F46d22559-c5c1-45fc-81bf-f541e2d5eefd)) returnstrue if A is a floating-point array andfalse otherwise. The floating-point types are single and double.

Examples

collapse all

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

% pi returns a floating-point value isfloat(pi)

% Complex numbers are floating-point values isfloat(3+7i)

% Single-precision numbers are floating-point values isfloat(realmax('single'))

% isfloat returns a logical value isfloat(isfloat(pi))

Input Arguments

collapse all

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).

Extended Capabilities

expand all

The isfloat function fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
