Example #1 :

# Ruby code for truncate() method

# declaring float values
a = 0.767

# declaring float values
b = 2999.011

# declaring float values
c = 2.0000

# TRUNCATED VALUES
puts "truncate a : #{a.truncate()}\n\n"

puts "truncate b : #{b.truncate()}\n\n"

puts "truncate c : #{c.truncate()}\n\n"

Output :

truncate a : 0

truncate b : 2999

truncate c : 2

Example #2 :

# Ruby code for truncate() method

# declaring float values
a = -83930.00000

# declaring float values
b = -66662999.11


# TRUNCATED VALUES
puts "truncate a : #{a.truncate()}\n\n"

puts "truncate b : #{b.truncate()}\n\n"

Output :

truncate a : -83930
