Ruby | Float class - value

Last Updated : 08 Jan, 2020

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

# 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

# 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
