Angle

Arduino library for basic math for Angles in degrees, minute, seconds and ten-thousands.

Description

Angle is an Arduino class to print, compare and do basic maths with angles in degrees, minutes seconds and ten-thousands. The class was created to be able to print an angle with minutes and seconds instead of as a floating point or radians.

To make the library more useful basic maths ( + - * / ) and comparisons ( == != < <= > >= ) are added to the class.

The library implements the Printable interface, allowing one to call

Serial.println(angle) or SD.print(angle)

Interface

Constructors

• Angle(int dd=0, int mm=0, int ss=0, int tt=0) create an Angle, default is zero.
• Angle(double alpha) create an Angle from a double.
• Angle(char * str) create an Angle from a string e.g. "45.31234".

base

• int sign() returns -1 or 1
• int degree() returns # degrees
• int minute() returns # minutes
• int second() returns # seconds
• int tenthousand() returns # ten-thousands of a second

Conversions

• double toDouble() returns the angle as a double (0..360.0, float on UNO)
• double toRadians() returns the angle in radians (0..TWO_PI)
• void fromRadian(double rad) create an angle from radians.

Equality operators

The library supports equality operator "==", "!=", "<" "<=" ">" and ">="

Math operators

• negate -angle
• addition and subtract add angles to angles
• multiplication and division multiply an angle with a double
• ratio ratio = Angle/Angle;

Operation

Note

The library has not been tested extensively and it could still contain bugs. Especially the constructor does not check input so use it carefully.
