IntegerToString

Syntax:

    stringvar = IntegerToString(Integer_variable)     'supports Integer.

Command Availability:

Available on all microcontrollers.

Explanation:

The IntegerToString function converts a number into a string. number can be any Integer variable, or a fixed number constant between -32768 and 32767 inclusive. For Byte numbers use ByteToString(), for Word numbers use WordToString(), for Long numbers use LongToString(), and for Single numbers use SingleToString().

The string variable stringvar contains the same number, represented as a string. The length of the string returned is 9 characters.

This function is especially useful if a number needs to be added to the end of a string, or if a custom data-sending routine only supports the output of string variables.

This function does not support conversion of hexadecimal number strings.

Note: When calling IntegerToString(), do not leave a space between the function name and the opening parenthesis — doing so produces a compiler error that is not obvious to diagnose. 

    ' use this -- no space between IntegerToString and the opening parenthesis
    IntegerToString(number_variable)

    ' do not use this -- note the space before the parenthesis
    IntegerToString (number_variable)

Example 1:

    'Set chip model
    #chip 16F1936

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

    Dim SensorReading as Integer

    'Take an A/D reading
    SensorReading = ReadAD10(AN0)

    'Create a string variable
    Dim OutVar As String

    'Fill string with sensor reading
    OutVar = IntegerToString(SensorReading)          ' <<< the IntegerToString instruction

    'Send
    HSerPrint OutVar
    HSerPrintCRLF

Key line: OutVar = IntegerToString(SensorReading) — converts the signed integer ADC reading into a decimal string, ready to be transmitted over the serial connection with HSerPrint.

Example 2:

    '''************************************************************************
    '''  PIC: 16F18855
    '''  Compiler: GCB
    '''  IDE: GCode
    '''  Board: Xpress Evaluation Board
    '''  Date: June 2021

    ' ----- Configuration
      'Chip Settings.
      #chip 16f18855,32
      #Config CLRE_ON
      #option Explicit

    ; ----- Define Hardware settings

      'Set the PPS of the RS232 ports.
      UNLOCKPPS
        RC0PPS = 0x0010     'RC0->EUSART:TX;
        RXPPS  = 0x0011     'RC1->EUSART:RX;
      LOCKPPS

    ; ----- Constants
      #define USART_BAUD_RATE 19200
      #define USART_TX_BLOCKING

    ; ----- Variables
    dim Integervar as Integer

    ; ----- Main body of program commences here.
    Integervar = -10

    do
       wait 100 ms

       HSerPrint IntegerToString( Integervar )          ' <<< the IntegerToString instruction
       HSerPrintCRLF
       wait 1 s
    loop
    end

Key line: HSerPrint IntegerToString( Integervar ) — converts the negative Integer value -10 to a string and prints it directly, without needing an intermediate string variable.
