## Function Documentation

template<typename T >

void piSwap | ( | T & | f,
|  | T & | s
| ) |  |
| inline

Templated function for swap two values.

Example:

int v1 = 1, v2 = 2;
piCout << v1 << v2; // 1 2
piSwap<int>(v1, v2);
piCout << v1 << v2; // 2 1
template<typename T >

void piSwapBinary | ( | T & | f,
|  | T & | s
| ) |  |
| inline

Templated function for swap two values without "=".

Example:

template<typename T >

int piRound | ( | const T & | v | ) |
| inline

Templated function return round of float falue.

Round is the nearest integer value
There are some macros:

- `piRoundf` for "float"
- `piRoundd` for "double"

Example:

piCout << piRoundf(0.6f) << piRoundd(0.2); // 1 0
piCout << piRoundf(-0.6f) << piRoundd(-0.2); // -1 0
template<typename T >

int piFloor | ( | const T & | v | ) |
| inline

Templated function return floor of float falue.

Floor is the largest integer that is not greater than value
There are some macros:

- `piFloorf` for "float"
- `piFloord` for "double"

Example:

piCout << piFloorf(0.6f) << piFloorf(0.2); // 0 0
piCout << piFloorf(-0.6f) << piFloorf(-0.2f); // -1 -1
template<typename T >

int piCeil | ( | const T & | v | ) |
| inline

Templated function return ceil of float falue.

Ceil is the smallest integer that is not less than value
There are some macros:

- `piCeilf` for "float"
- `piCeild` for "double"

Example:

piCout << piCeilf(0.6f) << piCeilf(0.2); // 1 1
piCout << piCeilf(-0.6f) << piCeilf(-0.2f); // 0 0
template<typename T >

T piAbs | ( | const T & | v | ) |
| inline

Templated function return absolute of numeric falue.

Absolute is the positive or equal 0 value
There are some macros:

- `piAbss` for "short"
- `piAbsi` for "int"
- `piAbsl` for "long"
- `piAbsll` for "llong"
- `piAbsf` for "float"
- `piAbsd` for "double"

Example:

piCout << piAbsi(5) << piAbsi(-11); // 5 11
piCout << piAbsf(-0.6f) << piAbsf(-0.2f); // 0.6 0.2
