    public static class MathUtility

    Methods

    Approximately(Single, Single)

    A faster drop-in replacement for Mathf.Approximately(a, b). Compares two floating point values and returns true if they are similar. As an optimization, this method does not take into account the magnitude of the values it is comparing. This method may not provide the same results as Mathf.Approximately for extremely large values

    Declaration
    public static bool Approximately(float a, float b)
    Parameters
    Type Name Description
    Single a

    The first float being compared

    Single b

    The second float being compared

    Returns
    Type Description
    Boolean

    ApproximatelyZero(Single)

    A slightly faster way to do Approximately(a, 0f).

    Declaration
    public static bool ApproximatelyZero(float a)
    Parameters
    Type Name Description
    Single a

    The floating point value to compare with 0

    Returns
    Type Description
    Boolean

    Clamp(Double, Double, Double)

    Constrain a value between a minimum and a maximum

    Declaration
    public static double Clamp(double input, double min, double max)
    Parameters
    Type Name Description
    Double input

    The input number

    Double min

    The minimum output

    Double max

    The maximum output

    Returns
    Type Description
    Double

    The input number, clamped between min and max

    FirstActiveFlagIndex(Int32)

    Return the index of the first flag bit set to true

    Declaration
    public static int FirstActiveFlagIndex(int value)
    Parameters
    Type Name Description
    Int32 value

    The flags value to check

    Returns
    Type Description
    Int32

    The index of the first active flag

    IsAxisAligned(Vector3)

    Checks if a vector is aligned with one of the axis vectors

    Declaration
    public static bool IsAxisAligned(this Vector3 v)
    Parameters
    Type Name Description
    Vector3 v

    The vector

    Returns
    Type Description
    Boolean

    True if the vector is aligned with any axis, otherwise false

    IsPositivePowerOfTwo(Int32)

    Check if a value is a positive power of two

    Declaration
    public static bool IsPositivePowerOfTwo(int value)
    Parameters
    Type Name Description
    Int32 value

    The value to check

    Returns
    Type Description
    Boolean

    True if the value is a positive power of two, false otherwise

    IsUndefined(Single)

    Is the float value infinity or NaN?

    Declaration
    public static bool IsUndefined(this float value)
    Parameters
    Type Name Description
    Single value

    The float value

    Returns
    Type Description
    Boolean

    True if the value is infinity or NaN (not a number), otherwise false

    ShortestAngleDistance(Double, Double, Double, Double)

    Finds the shortest angle distance between two angle values

    Declaration
    public static double ShortestAngleDistance(double start, double end, double halfMax, double max)
    Parameters
    Type Name Description
    Double start

    The start value

    Double end

    The end value

    Double halfMax

    Half of the max angle

    Double max

    The max angle value

    Returns
    Type Description
    Double

    The angle distance between start and end

    ShortestAngleDistance(Single, Single, Single, Single)

    Finds the shortest angle distance between two angle values

    Declaration
    public static float ShortestAngleDistance(float start, float end, float halfMax, float max)
    Parameters
    Type Name Description
    Single start

    The start value

    Single end

    The end value

    Single halfMax

    Half of the max angle

    Single max

    The max angle value

    Returns
    Type Description
    Single

    The angle distance between start and end
