# Ruby Float angle() method with example

• Last Updated : 07 Jan, 2020

Float angle() is a float class method which works on float values and works differently for both positive and negative values.

Syntax: float.angle()

Parameter: float value which is to be checked

Return: 0 for positive values Otherwise pi(3.141592653589793)

Example #1 :

 `# Ruby code for angle() method`` ` `# Initializing value``a = -``100``.``7` `- ``10``.``4``b = -``100` `* ``2000``.``0``c = (``22` `+ ``7``.``1``) * ``4`` ` `# Printing result``puts ``"angle value of a : #{a.angle}\n\n"``puts ``"angle value of b : #{b.angle}\n\n"``puts ``"angle value of c : #{c.angle}\n\n"`

Output :

```angle value of a : 3.141592653589793

angle value of b : 3.141592653589793

angle value of c : 0```

Example #2 :

 `# Ruby code for angle() method`` ` `# Initializing value``a = -``56``.``23333333``b = ``10000``.``0``c = -(``22` `+ ``7``.``1``)`` ` `# Printing result``puts ``"angle value of a : #{a.angle}\n\n"``puts ``"angle value of b : #{b.angle}\n\n"``puts ``"angle value of c : #{c.angle}\n\n"`

Output :

```angle value of a : 3.141592653589793

angle value of b : 0

angle value of c : 3.141592653589793```
