Ruby Float nan?() method with example

Ruby Float negative() method with example

Last Updated : 07 Jan, 2020

Float negative() is a float class method which checks whether the float value is negative.

Syntax: float.negative() Parameter: float value which is to be checked Return: Boolean value return false - if value is positive and return true - if value is negative

Example #1:

Ruby

# Ruby code for negative() method

# Initializing value
a = -100.7 - 10.4
b = -100 * 2000.0
c = (22 + 7.1) * 4

# Printing result
puts "a is negative : #{a.negative?}\n\n"
puts "b is negative : #{b.negative?}\n\n"
puts "c is negative : #{c.negative?}\n\n"

Output :

a is negative : true

b is negative : true

c is negative : false

Example #2:

Ruby

# Ruby code for negative() method

# Initializing value
a = -56.23333333
b = 10000.0
c = -(22 + 7.1)

# Printing Result
puts "a is negative : #{a.negative?}\n\n"
puts "b is negative : #{b.negative?}\n\n"
puts "c is negative : #{c.negative?}\n\n"

Output :

a is negative : true

b is negative : false

c is negative : true
