Float#() : () is a Float class method in Ruby which compares two Float values. 
Syntax:  Float.()

Parameter:  Float values

Return:  0  if a equals b, 1  if a > b, -1 if a < b
Code #1 : Example for () method Ruby 
# Ruby code for Float.<=>() method

# declaring float value
a = -100.7 - 10.4

# declaring float value
b = -100 * 2000.0

# declaring float value
c = -(22 + 7.1) * 4


# COMPARING TWO FLOAT VALUES
puts "Float a <=> b : #{a<=>b}\n\n"

# b
puts "Float b <=> c : #{b<=>c}\n\n"

# c
puts "Float a <=> c : #{c<=>a}\n\n"
Output : 
Float a  b : 1

Float b  c : -1

Float a  c : -1
Code #2 : Example for () method Ruby 
# Ruby code for Float.<=>() method

# declaring float value
a = -56.23333333

# declaring float value
b = 10000.0

# declaring float value
c = -(22 + 7.1)


# COMPARING TWO FLOAT VALUES
puts "Float a <=> b : #{a<=>b}\n\n"

# b
puts "Float b <=> c : #{b<=>c}\n\n"

# c
puts "Float a <=> c : #{c<=>a}\n\n"
Output : 
Float a  b : -1

Float b  c : 1
