The positive?() is an inbuilt function in Ruby returns boolean value true if rational number is greater than zero otherwise false
Syntax: rat.positive?()
Parameters: The function accepts no parameter
Return Value: It returns boolean value true if rational number is greater than zero otherwise false
Example 1:
# Ruby program for positive?() method # Initialize rational number rat1 = Rational(- 2 , 9 )
# Prints the boolean value puts rat1.positive?() |
Output:
false
Example 2:
# Ruby program for positive?() method # Initialize rational number rat1 = Rational( '1.23' )
# Prints the boolean value puts rat1.positive?() |
Output:
true
