isfloat

Determine if input is floating-point array

Syntax

tf = isfloat(A)

Description

tf = isfloat(A) returns true if A is a floating-point array and false otherwise. The floating-point types are single and double, and subclasses of single and double.

Examples

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

% pi returns a floating-point value
isfloat(pi)
ans =
     1
% Complex numbers are floating-point values
isfloat(3+7i)
ans =
     1
% Single-precision numbers are floating-point values
isfloat(realmax('single'))
ans =
     1
% isfloat returns a logical value
isfloat(isfloat(pi))
ans =
     0
