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 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 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 Float a c : 1
