If I is a grayscale or truecolor RGB image, it can be uint8 , uint16 , double , logical , single , or int If I is an indexed image, it can be uint8 , uint16 , double or logical. If I is a binary image, it must be logical. Data Types: single double int16 uint8 uint16 logical. Converted image, returned as a numeric array of the same size as the input image I. If the data type of the input image I is double , single , or logical , then the output pixel values are identical to the input pixel values. The im2double function does not rescale the output when the input image has single or double data type. If your input image is a truecolor image of data type single or double with pixel values outside this range, then you can use the rescale function to scale pixel values to the expected range [0, 1]. If I is a grayscale or truecolor image with data type uint8 , uint16 or int16 , then im2double rescales output pixel values to the range [0, 1]. If I is an indexed image with data type uint8 or uint16 , then im2double adds an offset of 1 to the output pixel values. This function fully supports tall arrays. For more information, see Tall Arrays.

Stores the sign, where 0 is double matlab and 1 is negative. For example, convert a signed integer to a double-precision floating-point number.

Integer and single precision arrays offer more memory-efficient storage than double precision. All numeric types support basic array operations, such as indexing, reshaping, and mathematical operations. The default is double precision. If you use the smallest integer type that accommodates your data, you can save memory and program execution time.

Floating-point data types allow for a varying number of digits after the decimal point, while fixed-point data types have a specific number of digits reserved before and after the decimal point. So, floating-point data types can represent a wider range of numbers than fixed-point data types. Due to limited memory for number representation and storage, computers can represent a finite set of floating-point numbers that have finite precision. This finite precision can limit accuracy for floating-point computations that require exact values or high precision, as some numbers are not represented exactly. Despite their limitations, floating-point numbers are widely used due to their fast calculations and sufficient precision and range for solving real-world problems.

KSSV on 11 Dec Other MathWorks country sites are not optimized for visits from your location. Gaps between single-precision numbers are larger than the gaps between double-precision numbers because there are fewer single-precision numbers.

The range of values is smaller compared to double-precision, but requires less memory. Version History Introduced before Ra. If I is a grayscale or truecolor image with data type uint8 , uint16 or int16 , then im2double rescales output pixel values to the range [0, 1].
