Ruby Float phase()用法及代碼示例


浮點數phase()是一個浮點類方法,它對浮點值起作用,並且對正值和負值都起作用。

用法: float.phase()

參數:要檢查的浮點值


返回:返回0表示正值,否則返回pi(3.141592653589793)

範例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"

輸出:

phase value of a:3.141592653589793

phase value of b:3.141592653589793

phase value of c:0

範例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"

輸出:

phase value of a:3.141592653589793

phase value of b:0

phase value of c:3.141592653589793
