Methods

AlmostEqual(double, double, double)

determine if two numbers are in the same range of each other
specifically useful when you want to know if two numbers are equal if you disregard tiny differences in values

public static bool AlmostEqual(double num1, double num2, double tolerance = 5E-324)

Parameters

num1 double

num2 double

tolerance double

the amount you want to compare the tow numbers against

Returns

bool

Remarks

this method should help with the fact that double values lose percision in arithmetic operations

AlmostEqual(double, double, int)

This method should help with the fact that double values lose percision in arithmetic operations. Determine if two numbers are in the same range of each other specifically useful when you want to know if two numbers are equal if you disregard tiny differences in values

public static bool AlmostEqual(double v1, double v2, int digits = 5)

Parameters

v1 double

v2 double

digits int

the difference between the two numbers will be rounded to this decimal point

Returns

bool

Remarks

Two numbers are almost equal to each other when their value is assessed against another number. As our environment is manufacturing and the most accurate devices (wire cutters) have a percision of 1E-5 meters we should round differences of the two numbers to that percision

AlmostEqual(double[], double[], int)

determines if two vectors are in the same range of each other
specifically useful when you want to know if two vectors are equal if you disregard tiny differences in values

public static bool AlmostEqual(double[] vector1, double[] vector2, int digits = 5)

Parameters

vector1 double[]

vector2 double[]

digits int

the difference between the two numbers will be rounded to this decimal point

Returns

bool

true if all members of each vector (array) are equal to a certain tolerance and false otherwise

Remarks

this method should help with the fact that double values lose percision in arithmetic operations

VectorsCross(double[], double[])

calculate the cross product of two vectors

public static double[] VectorsCross(double[] v1, double[] v2)

Parameters

v1 double[]

v2 double[]

Returns

double[]

V1 x V2 or {0,0,0} on error

VectorsDot(double[], double[])

calculate the dot product of two vectors

public static double VectorsDot(double[] v1, double[] v2)

Parameters

v1 double[]

v2 double[]

Returns

double

V1.V2 or -1 on error
