Ruby Float prev_float() method with example

Float prev_float() is a float class method which returns the previous representation of the floating point number.

Syntax: float.prev_float()

Parameter: float value to be passed

Return: Previous representation of the floating point number.

Example #1:




# Ruby code for prev_float() method
  
# Initializing value
a = 26.00/ 3
b = 8.0999
c = 3 + 105.003
  
# Printing Result
puts "previous Floating Point Number : #{a.prev_float}\n\n"
puts "previous Floating Point Number : #{b.prev_float}\n\n"
puts "previous Floating Point Number : #{c.prev_float}\n\n"

Output :

previous Floating Point Number : 8.666666666666664

previous Floating Point Number : 8.099899999999998

previous Floating Point Number : 108.00299999999999

Example #2:




# Ruby code for next_float() method
  
# Initializing value
a = 26.00
b = 8.0
  
# Printing result
puts "previous Floating Point Number : #{a.next_float}\n\n"
puts "previous Floating Point Number : #{b.prev_float}\n\n"

Output :

previous Floating Point Number : 26.000000000000004

previous Floating Point Number : 7.999999999999999
