Nov 06, 2024 am 08:48 AM32-bit to 16-bit Floating Point Conversion
Problem:
Convert 32-bit floating point numbers to 16-bit floating point numbers while minimizing precision loss. The converted values will be transmitted over a network, making size reduction a priority.
Solution:
This article introduces three solutions:
-
Encode IEEE 16-bit Floating Point:
- Uses a cross-platform library that supports IEEE 16-bit floating point format.
- This method is suitable for precise conversion between 32-bit and 16-bit floating point numbers.
-
Sample code:
<code class="cpp">auto encodedValue = encode_flt16(floatValue); auto decodedValue = decode_flt16(encodedValue);</code>
-
Linear Conversion to Fixed Point:
- Linearly maps the input 32-bit floating point number to a 16-bit fixed point format.
- This method is faster than IEEE conversion but less precise, especially around zero.
-
Sample code:
<code class="cpp">// Assuming 8-bit mantissa uint16_t fixedPointValue = (uint16_t)(floatValue * (1 << 8)); float decodedValue = (float)fixedPointValue / (1 << 8);</code>
-
Round-to-Nearest Conversion:
- Converts the 32-bit floating point number to a 16-bit floating point number using rounding to the nearest value.
- This method provides a balance between speed and precision.
-
Sample code:
<code class="cpp">// Assuming float16 type supports binary32 conversion float16 float16Value = float16(floatValue);</code>
Select the conversion method based on the specific requirements of your application, such as precision and performance.

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
