The F32 (aif32) data-type stores data as 32 bit single precision floating point values. It does not require any additional parameter to define the values.

Example: Create a F32 tensor
The tensor

\[ \left( \begin{array}{rrr} 0 & 1 & 2 \\ 3 & 4 & 5 \end{array}\right) \]

can be created with In C:

float example_data[] = {0.0f, 1.0f, 2.0f,
                        3.0f, 4.0f, 5.0f};
uint16_t example_shape[] = {2, 3};
aitensor_t example_tensor = {
    .dtype = aif32,
    .dim = 2,
    .shape = example_shape,
    .data = example_data
};

In C, C++ and on Arduino:

float example_data[] = {0.0f, 1.0f, 2.0f,
                        3.0f, 4.0f, 5.0f};
uint16_t example_shape[] = {2, 3};
aitensor_t example_tensor = AITENSOR_2D_F32(example_shape, example_data);

Example: Create a F32 scalar
Either create it as a normal float value

float scalar = 42.0f;

or with the alias

aiscalar_f32_t scalar = 42.0f;

Example: Print a F32 tensor to the console

print_aitensor(&example_tensor);

Example: Print a F32 scalar to the console

print_aiscalar(&scalar, aif32);

Typedef Documentation

aiscalar_f32_t

typedef float aiscalar_f32_t

Scalar for F32 (aif32) data-type.

This is only an alias for a float value for consistency.
You can create a F32 scalar either as a normal float value

float scalar = 42.0f;

or with the alias

aiscalar_f32_t scalar = 42.0f;

You can print the scalar to the console with

print_aiscalar(&scalar, aif32);

or by using

aimath_f32_print_aiscalar(&scalar, printf);

Function Documentation

aimath_f32_print_aiscalar()

void aimath_f32_print_aiscalar

(

const void *

scalar

)

Printing a F32 scalar to console.

For users the function

print_aiscalar(&scalar, aif32);

is prefered.

Parameters

*scalar

The scalar (type: float) to print.

aimath_f32_print_aitensor()

void aimath_f32_print_aitensor

(

const aitensor_t *

tensor

)

Printing a F32 tensor to console.

For users the function

print_aitensor(&tensor);

is prefered.

Parameters

*tensor

The tensor to print.

Variable Documentation

aif32

const aimath_dtype_t* aif32

extern
