Ruby 整数 succ()函数与示例
Ruby 中的succ函数返回数字的直接后继,即返回数字 + 1 。如果使用浮点值,则会引发错误消息。
Syntax: number.succ
Parameter: The function takes the integer whose next is to be returned.
Return Value: The function returns the immediate successor of the number, i.e., it returns number + 1
示例 1:
Ruby
# Ruby program for succ function
# Initializing the numbers
num1 = 100
num2 = 17
num3 = -90
num4 = -29
# Printing the next value
puts num1.succ
puts num2.succ
puts num3.succ
puts num4.succ
Ruby
# Ruby program for succ function
# Initializing the numbers
num1 = 19
num2 = -17
num3 = -18
num4 = 16
# Printing the succ value
puts num1.succ
puts num2.succ
puts num3.succ
puts num4.succ
输出:
101
18
-89
-28
