Float#truncate() is a float class method which return a truncated value rounded to ndigits decimal digits precision.

Syntax: float.truncate() Parameter: float value as argument Return: truncated value rounded to nearest precision If precision is -ve : integer with at least ndigits.abs trailing zeros If ndigits is +ve : a floating point number, otherwise integer

Example #1 :

Ruby

# 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

# 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

truncate b : -66662999
