Hi;
when I write:

Code: Select all

DebugPrintf ("\n precision %d",3.75);

it displays a huge random No.

I think the problem in the DebugDisplay.cpp:

Code: Select all

int DebugPrintf (const char* str, ...)

/*** integers ***/
					case 'd':
					case 'i': {
						int c = va_arg (args, int);
						char str[32]={0};
						itoa_s (c, 10, str);
						DebugPuts (str);
						i++;		// go to next character
						break;
					}

plz help me to display many digits Number!

Having not seeing this really large number, I am willing to bet that it's 1081081856

Am I right?




Here is how I made my guess:

You are passing a parameter of 3.75, which is a floating point value. Your DebugPrintf is interpreting it as an integer.

Because a computer can only deal with integers, it has no idea about floating points. Therefore, there exits the IEEE 754 standard for representing floating point values as integers.

http://en.wikipedia.org/wiki/Floating_p ... esentation has more information about the specific format of floating point numbers.
