Getting multiplicative identity in Julia – one() Method
The one()
is an inbuilt function in julia which is used to return a multiplicative identity of the specified value x, where x is a value such that one(x)*x == x*one(x) == x.
Syntax:
one(x)
or
one(T::type)Parameters:
- : Specified value.
- one(T::type): Specified number type.
Returns: It returns a multiplicative identity of the specified value x, where x is a value such that one(x)*x == x*one(x) == x.
Example 1:
# Julia program to illustrate # the use of one() method # Getting return a multiplicative # identity of the specified value x println(one( 0 )) println(one( 1 )) println(one( 5 )) println(one( 5.9 )) |
Output:
1 1 1 1.0
Example 2:
# Julia program to illustrate # the use of one() method # Getting return a multiplicative # identity of the specified number type println(one( Int )) println(one(String)) |
