How can we check if a float value is positive in Ruby?
okwudili onyejiaku
Overview
Numbers greater than 0 are positive numbers. We can check if a number is greater than 0 by using the positive? method. This method returns either true or false.
Syntax
float_value.positive?
Parameters
float_value: This is the float value that we want to check to see if it is greater than 0.
Return value
The result of this method is always a boolean value.
If the float_value is greater than 0, then true is returned. However, if the float_value is not greater than 0, then false is returned.
Code example
# create some values f1 = 3.444 f2 = 0.0 f3 = 0.3 f4 = 100 / 0.0 # check if greater than 0 # and print results puts f1.positive? # true puts f2.positive? # false puts f3.positive? # true puts f4.positive? # true
Check if float values are greater than 0
Code explanation
- Lines 2–5: We create the float values
f1,f2,f3, andf4. - Lines 9–12: We invoke the
positive?method on the float values we created, and we print the returned values to the console.
