SingleToHex

Syntax:

    stringvar = SingleToHex(number)

Command Availability:

Available on all microcontrollers.

Explanation:

The SingleToHex function converts a Single (floating-point) number into hexadecimal format, representing its raw 4-byte in-memory encoding rather than a decimal-to-hex conversion of its numeric value. The input number should be a Single variable. After running the function, the string variable stringvar contains an 8-digit hexadecimal number (4 bytes, since a Single occupies 32 bits).

Example:

    'Set chip model
    #chip 16F1936

    'Set up hardware serial connection
    #define USART_BAUD_RATE 9600
    #define USART_TX_BLOCKING

    Dim CurrSingle As Single
    CurrSingle = 3.14159

    HSerPrint SingleToHex(CurrSingle)          ' <<< the SingleToHex instruction
    HSerPrintCRLF

Key line: SingleToHex(CurrSingle) — returns the 8-digit hex representation of the 4 raw bytes that make up the Single value, useful for inspecting or transmitting a floating-point value byte-for-byte.
