Ruby Float to_r() 方法与示例

Float to_r()是一个浮点类方法，它返回浮点值的有理形式。

Syntax: float.to_r()

Parameter: float value as argument

Return: Rational form representation of the float value.

示例 #1：

# Ruby code for to_r() method
  
# Initializing values
a = 2.0
b = 9.99991
  
# Printing result
puts "Rational form of a : #{a.to_r}\n\n"
puts "Rational Form of b : #{b.to_r}\n\n"

输出 ：

Rational form of a : 2/1

Rational Form of b : 21990034643427/2199023255552

示例 #2：

# Ruby code for to_r() method
  
# Initializing value
a = 0.767
b = 2797999.011
  
# Printing result
puts "Rational form of a : #{a.to_r}\n\n"
puts "Rational Form of b : #{b.to_r}\n\n"

输出 ：

Rational form of a : 6908521828386341/9007199254740992

Rational Form of b : 375541070202667/134217728
