Function Documentation

template<class T >

const T& epicsMin ( const T &  a, const T &  b  )

inline

Returns the smaller of a or b compared using a<b.

Definition at line 30 of file epicsAlgorithm.h.

template<>

const float& epicsMin ( const float &  a, const float &  b  )

inline

Returns the smaller of a or b compared using a<b.

Note

If b is a NaN the above template returns a, but should return NaN. These specializations ensure that epicsMin(x,NaN) == NaN

Definition at line 42 of file epicsAlgorithm.h.

template<>

const double& epicsMin ( const double &  a, const double &  b  )

inline

Returns the smaller of a or b compared using a<b.

Note

If b is a NaN the above template returns a, but should return NaN. These specializations ensure that epicsMin(x,NaN) == NaN

Definition at line 54 of file epicsAlgorithm.h.

template<class T >

const T& epicsMax ( const T &  a, const T &  b  )

inline

Returns the larger of a or b compared using a<b.

Definition at line 64 of file epicsAlgorithm.h.

template<>

const float& epicsMax ( const float &  a, const float &  b  )

inline

Returns the larger of a or b compared using a<b.

Note

If b is a NaN the above template returns a, but should return NaN. These specializations ensure that epicsMax(x,NaN) == NaN

Definition at line 76 of file epicsAlgorithm.h.

template<>

const double& epicsMax ( const double &  a, const double &  b  )

inline

Returns the larger of a or b compared using a<b.

Note

If b is a NaN the above template returns a, but should return NaN. These specializations ensure that epicsMax(x,NaN) == NaN

Definition at line 88 of file epicsAlgorithm.h.

template<class T >

void epicsSwap ( T &  a, T &  b  )

inline

Swaps the values of a and b.

Note

The data type must support both copy-construction and assignment.
