Float phase() is a float class method which works on float values and works differently for both positive and negative values.
Syntax: float.phase()
Parameter: float value which is to be checked
Return: return 0 for positive values otherwise return pi(3.141592653589793)
Example #1:
a = - 100 . 7 - 10 . 4
b = - 100 * 2000 . 0
c = ( 22 + 7 . 1 ) * 4
puts "phase value of a : #{a.phase}\n\n"
puts "phase value of b : #{b.phase}\n\n"
puts "phase value of c : #{c.phase}\n\n"
|
Output :
phase value of a : 3.141592653589793
phase value of b : 3.141592653589793
phase value of c : 0
Example #2:
a = - 56 . 23333333
b = 10000 . 0
c = -( 22 + 7 . 1 )
puts "phase value of a : #{a.phase}\n\n"
puts "phase value of b : #{b.phase}\n\n"
puts "phase value of c : #{c.phase}\n\n"

Output :
phase value of a : 3.141592653589793
phase value of b : 0
phase value of c : 3.141592653589793
