用法： float.rationalize()

参数：浮点值作为参数

返回：简单近似值

范例1：

# Ruby program for rationalize() method 
  
# Initialize value 
a = 0.767
b = 2999.011
  
# Printing result 
puts "Rationalizing a:#{a.rationalize}\n\n"
puts "Rationalizing b:#{b.rationalize}\n\n"

输出：

Rationalizing a:767/1000

Rationalizing b:2999011/1000

范例2：

# Ruby code for rationalize() method 
  
# Initialize value 
a = 0.767
b = 2999.011
c = 2.0000
  
# Printing result 
puts "Rationalizing a:#{a.rationalize(0.01)}\n\n"
puts "Rationalizing b:#{b.rationalize(0.00001)}\n\n"
puts "Rationalizing c:#{c.rationalize(0.1)}\n\n"

输出：

Rationalizing a:10/13

Rationalizing b:1634461/545

Rationalizing c:2/1
