Ruby Float phase() 方法与示例

Float phase()是一个浮点类方法，它适用于浮点值，并且对正值和负值的工作方式不同。

Syntax: float.phase()

Parameter: float value which is to be checked

Return: return 0 for positive values otherwise return pi(3.141592653589793)

示例 #1：

# Ruby code for phase() method
  
# Initializing value
a = -100.7 - 10.4
  
b = -100 * 2000.0
  
c = (22 + 7.1) * 4
  
# Printing result
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"

输出 ：

phase value of a : 3.141592653589793

phase value of b : 3.141592653589793

phase value of c : 0

示例 #2：

# Ruby code for phase() method
  
# Initializing value
a = -56.23333333
b = 10000.0
c = -(22 + 7.1)
  
# Printing result
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"

输出 ：

phase value of a : 3.141592653589793

phase value of b : 0

phase value of c : 3.141592653589793
