Ruby Float fdiv()方法及示例
Float fdiv()是一个float类方法,返回p/q形式的除法值。
语法: float.fdiv()
参数: 要除的值–p和q
返回: 除法值–商数
例子 #1 :
# Ruby program for fdiv() method
# Initializing value
a = 2.0.numerator()
# returning machine dependent result
puts "numerator : #{a}\n\n"
# using as a numerator
puts "Division int/float : #{a.fdiv(4)}\n\n"
puts "Division float/float : #{a.fdiv(4.0)}\n\n"
输出:
numerator : 2
Division int/float : 0.5
Division float/float : 0.5
例子#2 。
# Ruby program for fdiv() method
# Initializing value
a = 0.numerator()
# Printing result
puts "numerator : #{a}\n\n"
puts "Division int/float : #{a.fdiv(4)}\n\n"
puts "Division float/float : #{a.fdiv(4.0)}\n\n"
输出:
numerator : 0
Division int/float : 0.0
Division float/float : 0.0
