红宝石 |浮点类值
Float#() : ()是 Ruby 中的 Float 类方法,用于比较两个 Float 值。
Syntax: Float.()
Parameter: Float values
Return: 0 if a equals b, 1 if a > b, -1 if a < b
代码 #1:() 方法的示例
# Ruby code for Float.<=>() method
# declaring float value
a = -100.7 - 10.4
# declaring float value
b = -100 * 2000.0
# declaring float value
c = -(22 + 7.1) * 4
# COMPARING TWO FLOAT VALUES
puts "Float a <=> b : #{a<=>b}\n\n"
# b
puts "Float b <=> c : #{b<=>c}\n\n"
# c
puts "Float a <=> c : #{c<=>a}\n\n"
输出 :
Float a b : 1
Float b c : -1
Float a c : -1
代码 #2:() 方法的示例
# Ruby code for Float.<=>() method
# declaring float value
a = -56.23333333
# declaring float value
b = 10000.0
# declaring float value
c = -(22 + 7.1)
# COMPARING TWO FLOAT VALUES
puts "Float a <=> b : #{a<=>b}\n\n"
# b
puts "Float b <=> c : #{b<=>c}\n\n"
# c
puts "Float a <=> c : #{c<=>a}\n\n"
输出 :
Float a b : -1
Float b c : 1
Float a c : 1
