Ruby Float arg() 方法与示例
Float arg()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.arg()
Parameter: float value which is to be checked
Return: return 0 for positive values. Otherwise pi(3.141592653589793)
示例 #1:
# Ruby code for arg() method
# Initializing values
a = -100.7 - 10.4
b = -100 * 2000.0
c = (22 + 7.1) * 4
# Printing result
puts "arg value of a : #{a.arg}\n\n"
puts "arg value of b : #{b.arg}\n\n"
puts "arg value of c : #{c.arg}\n\n"
输出 :
arg value of a : 3.141592653589793
arg value of b : 3.141592653589793
arg value of c : 0
示例 #2:
# Ruby code for arg() method
# Initializing value
a = -56.23333333
b = 10000.0
c = -(22 + 7.1)
# Printing result
puts "arg value of a : #{a.arg}\n\n"
puts "arg value of b : #{b.arg}\n\n"
puts "arg value of c : #{c.arg}\n\n"
输出 :
arg value of a : 3.141592653589793
arg value of b : 0
arg value of c : 3.141592653589793
