Ruby Float magnitude()用法及代碼示例


浮點數magnitude()是一個浮點類方法,它對浮點值起作用並將其轉換為絕對形式。

用法: float.magnitude()

參數:將轉換為絕對值的浮點值


返回:傳遞的浮點值的絕對值

範例1:

# Ruby program for magnitude() method 
  
# Initializing value 
a = -56.23333333
b = -10000.0
c = -(22 + 7.1) 
  
# Printing result 
puts "magnitude value of a:#{a.magnitude}\n\n"
puts "magnitude value of b:#{b.magnitude}\n\n"
puts "magnitude value of c:#{c.magnitude}\n\n"

輸出:

magnitude value of a:56.23333333

magnitude value of b:10000.0

magnitude value of c:29.1

範例2:

# Ruby program for magnitude() method 
  
# Initializing value 
a = -100.7 - 10.4
b = -100 * 2000.0
c = -(22 + 7.1) * 4
  
# Printing result 
puts "magnitude value of a:#{a.magnitude}\n\n"
puts "magnitude value of b:#{b.magnitude}\n\n"
puts "magnitude value of c:#{c.magnitude}\n\n"

輸出:

magnitude value of a:111.10000000000001

magnitude value of b:200000.0

magnitude value of c:116.4
