	The constant pi to high precision.

Functions
template<class NUMBER>
NUMBER	stir::square (const NUMBER &x)
	returns the square of a number, templated.

Variables
constexpr double	stir::speed_of_light_in_mm_per_ps = 0.299792458
	Define the speed of light in mm / ps.
constexpr double	stir::speed_of_light_in_mm_per_ps_div2 = speed_of_light_in_mm_per_ps * 0.5
	This ratio is used often.

This include file defines some commonly used macros, templates and functions in an attempt to smooth out some system dependencies. It also defines some functions which are used very often.

Macros and system dependencies:

• macros for namespace support: #defines START_NAMESPACE_STIR etc.

• preprocessor definitions which attempt to determine the operating system this is going to run on. use as "#ifdef <strong>OS_WIN</strong> ... #elif ... #endif" Possible values are OS_WIN, OS_MAC, OS_VAX, OS_UNIX The OS_UNIX case has 'subbranches'. At the moment we attempt to find out on OS_AIX, OS_SUN, OS_OSF, OS_LINUX. (If the attempts fail to determine the correct OS, you can pass the correct value as a preprocessor definition to the compiler)

• #includes cstdio, cstdlib, cstring, cmath, cassert

stir namespace members declared here

• const double _PI

• inline template <class NUMBER> NUMBER square(const NUMBER &x)

stir include files included here

• stir/config.h sets various preprocessor defines (generated from STIRConfig.in)
