uint32 swapIfLittleEndian (  const uint32  v  )  throw ()

uint64 swapIfLittleEndian (  const uint64  v  )  throw ()

Swaps the byte order of a 64-bit int if the CPU is little-endian.

uint32 littleEndianInt (  const char *const   bytes  )  throw ()

Turns 4 bytes into a little-endian integer.

uint16 littleEndianShort (  const char *const   bytes  )  throw ()

Turns 2 bytes into a little-endian integer.

uint32 bigEndianInt (  const char *const   bytes  )  throw ()

Turns 4 bytes into a big-endian integer.

uint16 bigEndianShort (  const char *const   bytes  )  throw ()

Turns 2 bytes into a big-endian integer.

int littleEndian24Bit (  const char *const   bytes  )  throw ()

Converts 3 little-endian bytes into a signed 24-bit value (which is sign-extended to 32 bits).

int bigEndian24Bit (  const char *const   bytes  )  throw ()

Converts 3 big-endian bytes into a signed 24-bit value (which is sign-extended to 32 bits).

void littleEndian24BitToChars (  const int  value, char *const   destBytes )  throw ()

Copies a 24-bit number to 3 little-endian bytes.

void bigEndian24BitToChars (  const int  value, char *const   destBytes )  throw ()

Copies a 24-bit number to 3 big-endian bytes.

int roundDoubleToInt (  const double  value  )  throw ()

Fast floating-point-to-integer conversion. This is faster than using the normal c++ cast to convert a double to an int, and it will round the value to the nearest integer, rather than rounding it down like the normal cast does. Note that this routine gets its speed at the expense of some accuracy, and when rounding values whose floating point component is exactly 0.5, odd numbers and even numbers will be rounded up or down differently. For a more accurate conversion, see roundDoubleToIntAccurate().

int roundDoubleToIntAccurate (  const double  value  )  throw ()

Fast floating-point-to-integer conversion. This is a slightly slower and slightly more accurate version of roundDoubleToInt(). It works fine for values above zero, but negative numbers are rounded the wrong way.

int roundFloatToInt (  const float  value  )  throw ()

Fast floating-point-to-integer conversion. This is faster than using the normal c++ cast to convert a float to an int, and it will round the value to the nearest integer, rather than rounding it down like the normal cast does. Note that this routine gets its speed at the expense of some accuracy, and when rounding values whose floating point component is exactly 0.5, odd numbers and even numbers will be rounded up or down differently.
