## Deprecated endian conversion routines
It is recommended to use csLittleEndian, csBigEndian, csIEEEfloat, csGetFromAddress or csSetToAddress for the tasks below.
static float | csBigEndianFloat (float f)
| Convert a big-endian floating-point number to machine format.
static uint32 | csBigEndianLong (uint32 l)
| Convert a long from big-endian to machine format.
static uint64 | csBigEndianLongLong (uint64 l)
| Convert a longlong from big-endian to machine format.
static uint16 | csBigEndianShort (uint16 s)
| Convert a short from big-endian to machine format.
static int64 | csDoubleToLongLong (double d)
| Convert a double to a cross-platform 64-bit format (no endianess adjustments!).
static int32 | csFloatToLong (float f)
| Convert a float to a cross-platform 32-bit format (no endianess adjustments!).
static short | csFloatToShort (float f)
| Convert a float to a cross-platform 16-bit format (no endianess adjustments!).
static float | csLittleEndianFloat (float f)
| Convert a little-endian floating-point number to machine format.
static uint32 | csLittleEndianLong (uint32 l)
| Convert a long from little-endian to machine format.
static uint64 | csLittleEndianLongLong (uint64 l)
| Convert a longlong from little-endian to machine format.
static uint16 | csLittleEndianShort (uint16 s)
| Convert a short from little-endian to machine format.
static double | csLongLongToDouble (int64 i)
| Convert a 64-bit cross-platform double to native format (no endianess adjustments!).
static float | csLongToFloat (int32 l)
| Convert a 32-bit cross-platform float to native format (no endianess adjustments!).
static float | csShortToFloat (short s)
| Convert a 16-bit cross-platform float to native format (no endianess adjustments!).
## Defines
#define | csQroundSure(x) (int ((x) + ((x < 0) ? -0.5 : +0.5)))
