Float#-() : -() is a Float class method in Ruby which return difference of two Float numbers.
Syntax: Float.-() Parameter: Float values Return: Difference of the two Float values
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
# a 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 : 199888.9 Float b - c : -199883.6 Float a - c : -5.299999999999997
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 )
# a 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 : -10056.23333333 Float b - c : 10029.1 Float a - c : 27.13333333
