Displaying a Floating Point Number

Version 1
    Question: How to display a floating point number on the LCD when using the PSoC C-compiler?



    A floating point number can be converted to ascii using the ftoa function and then displayed on an LCD using the LCD_PrString function.  An example code snippet is shown below.

    #include "stdlib.h"

    #include "string.h"

    void main(void)
       float MyFloat;
       int Status;
       char* buf;

       MyFloat = 1.2345;
       buf = ftoa(MyFloat, &Status);

    The same approach may be used to convert a float to ascii and send it over UART.  Instead of the LCD_PrString function, UART_PutString function should be used.
