Member Function Documentation

static bool FWMath::close (  double  one, double  two )  [inline, static]

Tests whether two doubles are close enough to be declared equal. Returns: true if parameters are at most epsilon apart, false otherwise

static double FWMath::dBm2mW (  double  dBm  )  [inline, static]

convert a dBm value into milli Watt

static double FWMath::div (  double  dividend, double  divisor )  [inline, static]

Returns the result of a whole-numbered division.

static double FWMath::max (  double  a, double  b )  [inline, static]

Returns: greater of the given parameters

static double FWMath::mod (  double  dividend, double  divisor )  [inline, static]

Returns the rest of a whole-numbered division.

static int FWMath::round (  double  d  )  [inline, static]

Returns: integer that corresponds to rounded double parameter

static int FWMath::sign (  double  i  )  [inline, static]

Returns: 1 if parameter greater or equal zero, -1 otherwise

static int FWMath::stepfunction (  double  i  )  [inline, static]

Returns: 0 if i is close to 0, 1 if i is positive greater epsilon, -1 if it is negative smaller epsilon.

static double FWMath::torDist (  double  x1, double  x2, double  y1, double  y2 )  [inline, static]

helper function, returns squared euclidean distance makes code less messy
