#!/usr/bin/ruby num = 12.40 puts num.floor # 12 puts num + 10 # 22.40 puts num.integer? # false as num is a float. This will produce the following result −

sqrt ( 24 ) #=> 4 Integer . sqrt ( 25 ) #=> 5 Integer . sqrt ( 10 ** 400 ) #=> 10**200 something of type integer. But anyhow, I really don't see way C does it as great either. Many more modern languages have separate syntaxes for floor division and float-returning division. "Regular math" tends to use different symbols also. What would be the downside if C (or Ruby… 1/21/2019 2/21/2020 If you need just the integer portion, use integers with the / operator, or the Numeric#div method: quotient = 208 / 11 #=> 18 quotient = 208.0.div 11 #=> 18 If you need just the remainder, use the % operator or the Numeric#modulo method: Ruby supports a rich set of operators, as you'd expect from a modern language.
