How to check if a float value in Ruby is less than 0
Overview
In Ruby, we can check if the float value is less than zero (0) using the negative? method.
Syntax
float_value.negative?
Parameters
float_value: This is the value that we want to check.
Return value
It returns true if the float_value is less than 0. Otherwise, it returns false.
Code example
# create some float valuesf1 = 2.3/0.0 # Infinityf2 = -1.0f3 = -9.2333/0.0 # -Infinityf4 = 0.0/0.0f5 = 221.2222# check if less than 0puts f1.negative?puts f2.negative?puts f3.negative?puts f4.negative?puts f5.negative?
Explanation
- Lines 2-6: We initialize the float variables
f1,f2,f3,f4,f5, andf6. - Lines 9-13: We invoke the
negative?method on the float variables we’ve created and print the results on the console.
