Ruby Float absolute()方法及示例
Float abs() 是一个float类的方法,它对浮点数进行处理并将其转换为绝对形式。
语法: float.abs()
参数: 要转换为绝对值的浮点数值
返回: 所传递的浮点数值的绝对值
例子 #1 :
# Ruby code for abs() method
# Initializing value
a = -56.23333333
b = -10000.0
c = -(22 + 7.1)
# Printing result
puts "absolute value of a : #{a.abs}\n\n"
puts "absolute value of b : #{b.abs}\n\n"
puts "absolute value of c : #{c.abs}\n\n"
输出:
absolute value of a : 56.23333333
absolute value of b : 10000.0
absolute value of c : 29.1
例子 #2 :
# Ruby code for abs() method
# Initializing value
a = -100.7 - 10.4
b = -100 * 2000.0
c = -(22 + 7.1) * 4
# Printing result
puts "absolute value of a : #{a.abs}\n\n"
puts "absolute value of b : #{b.abs}\n\n
puts "absolute value of c : #{c.abs}\n\n"
输出:
absolute value of a : 111.10000000000001
absolute value of b : 200000.0
absolute value of c : 116.4
