T floating_point_emulation::detail::load ( double  value )

inline

Definition at line 237 of file floating_point_emulation.hpp.

void floating_point_emulation::detail::sal ( double &  lhs, unsigned  rhs  )

inline

Shift arithmetically left.

Shifting of floating point values doesn't exist so it's emulated by a multiplication. This function allows tidiv::idiv() to contain generic code.

Parameters

lhs	The value to `shift'.
rhs	The number of bits to `shift'.

Definition at line 287 of file floating_point_emulation.hpp.

Referenced by floating_point_emulation::detail::tidiv< T, 8 >::idiv().

void floating_point_emulation::detail::sal ( Sint32 &  lhs, unsigned  rhs  )

inline

Shift arithmetically left.

Parameters

lhs	The value to shift.
rhs	The number of bits to shift.

Definition at line 299 of file floating_point_emulation.hpp.

void floating_point_emulation::detail::sar ( double &  lhs, unsigned  rhs  )

inline

Shift arithmetically right.

Shifting of floating point values doesn't exist so it's emulated by a division. This function allows tidiv::idiv() to contain generic code.

Parameters

lhs	The value to `shift'.
rhs	The number of bits to `shift'.

void floating_point_emulation::detail::sar ( Sint32 &  lhs, unsigned  rhs  )

Parameters

lhs	The value to shift.
rhs	The number of bits to shift.
