Ruby Float divmod() 方法与示例
Float divmod()是一个浮点类方法,它返回一个数组,该数组具有两个数相除的商和余数。
Syntax: float.divmod()
Parameter: float values – dividend and divisor
Return: An array with quotient and remainder.
示例 #1:
Ruby
# Ruby code for divmod() method
# Initializing value
a = 4.0
b = 2.0
# Printing result
puts "Division a/b : #{a.divmod(b)}\n\n"
puts "Division b/a : #{b.divmod(a)}\n\n"
Ruby
# Ruby program for divmod() method
# Initializing value
a = 0
b = 2.0
# dividing by zero - gives error
puts "Division a/b : #{a.divmod(b)}\n\n"
puts "Division b/a : #{b.divmod(a)}\n\n"
输出 :
Division a/b : [2, 0.0]
Division b/a : [0, 2.0]
示例 #2:
红宝石
# Ruby program for divmod() method
# Initializing value
a = 0
b = 2.0
# dividing by zero - gives error
puts "Division a/b : #{a.divmod(b)}\n\n"
puts "Division b/a : #{b.divmod(a)}\n\n"
输出 :
source_file.rb:8:in `divmod': divided by 0 (ZeroDivisionError)
from source_file.rb:8:in `'
Division a/b : [0, 0.0]
