Ruby Float fdiv() 方法与示例
Float fdiv()是一个浮点类方法,它返回 p/q 形式的除法值。
Syntax: float.fdiv()
Parameter: values to divide – p and q
Return: Division value – Quotient
示例 #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
示例 #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
