72. Transmit Float as Byte Stream Using Union

In embedded systems, floating-point values are often transmitted over UART or SPI as raw bytes. You are given a float value and must simulate how it would be serialized into 4 bytes.

Your task is to:

1. Define a union that contains:
   • A float variable
   • A uint8_t[4] byte array
2. Read a float from input
3. Use the union to access and print the 4 individual bytes in order (LSB first)
    

Example-1

Input: 1.0
Output:
Byte 0: 0  
Byte 1: 0  
Byte 2: 128  
Byte 3: 63

Example-2

Input: -2.5
Output (example):
Byte 0: 0  
Byte 1: 0  
Byte 2: 32  
Byte 3: 192
