Function Documentation

void hel_MathExtractDigits	(	u32	Value,
		u8 *	pOut,
		u32	nDigits
	)

Extract digits from a value.

The hel_MathExtractDigits can be used to extract digits from a given value. This is handy when dealing with score display.

Parameters:

[in]	Value	Source value from where to extract the digits from
[out]	pOut	Destination buffer which receives the extracted digits
[in]	nDigits	Amount of digits to extract

The following example extracts the digits from 1234. The result is stored in Buffer which will contain the following values afterwards: 1,2,3,4

    u8 Buffer[4];

    hel_MathExtractDigits(1234, Buffer, 4);

Note:

The same result can be achieved with some C modulus/sprintf/whatever. Obviously, this slow! hel_MathExtractDigits is more designed for speed. It uses the BIOS functions instead.
