Function Documentation

uint16_t c::include::bcd::mul_dig_pair ( const packed_BCD_pair  ab, const packed_BCD_pair  cd  )

inline

Multiply a pair of BCD bytes.

Parameters

[in]	ab	The first byte, which gets split into nibbles a and b
[in]	cd	The second byte, which gets split into nibbles c and d

Remarks

This function runs takes \(Θ(1)\) time

Returns

\(100 \cdot a \cdot c + 10 \cdot (a \cdot d + b \cdot c) + b \cdot d\)

Here is the caller graph for this function:

void print_bcd

(

const BCD_int

x

)

Print a BCD_int to the screen.

Parameters

[in]

x

The BCD_int you'd like to print

Remarks

This function runs takes \(Θ(\log_{100}(x))\) time

Here is the caller graph for this function:

void print_bcd_ln

(

const BCD_int

x

)

Print a BCD_int to the screen and append a newline.

Parameters

[in]

x

The BCD_int you'd like to print

Remarks

This function runs takes \(Θ(\log_{100}(x))\) time
