Method Detail

normalizeRadians

public static double normalizeRadians(double iAngle)

Modulates angle.

Details: normalizeRadians modulates the given angle, expressed in radians, so that it falls between -pi and +pi.

Parameters:

iAngle - angle to normalize

Returns:

normalized angle

normalizeDegrees

public static double normalizeDegrees(double iAngle)

Modulates angle.

Details: normalizeRadians modulates the given angle, expressed in degrees, so that it falls between -pi and +pi.

Parameters:

iAngle - angle to normalize

Returns:

normalized angle

isReal

public static boolean isReal(float iValue)

Tests if value is real.

Details: isReal returns true if the given value is "real." In other words, isReal returns true if the value is neither infinite nor NaN, false otherwise.

Parameters:

iValue - value to test

Returns:

true iff real

isReal

public static boolean isReal(double iValue)

Tests if value is real.

Details: isReal returns true if the given value is "real." In other words, isReal returns true if the value is neither infinite nor NaN, false otherwise.

Parameters:

iValue - value to test

Returns:

true iff real
