浮點數angle()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.angle()
參數:要檢查的浮點值
返回:0為正值,否則為pi(3.141592653589793)
範例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"
輸出:
angle value of a:3.141592653589793 angle value of b:3.141592653589793 angle value of c:0
範例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"
輸出:
angle value of a:3.141592653589793 angle value of b:0 angle value of c:3.141592653589793
