Checking if a number is odd in Julia - isodd() Method

Checking type validity of a value in Julia - isvalid() Method

Last Updated : 01 Apr, 2020

The isvalid() is an inbuilt function in julia which is used to return true if the specified value is valid for its type. The type can be either AbstractChar or String or SubString{String}.

Syntax: isvalid(value) or isvalid(T, value) Parameters:

Value: Specified value.

T: Specified type.

Returns: It returns true if the specified value is valid for its type else returns false.

Example 1:

Python

# Julia program to illustrate 
# the use of isvalid() method
 
# Getting true if the specified value
# is valid for its type else returns false.
println(isvalid(Char(2)))
println(isvalid(Char('a')))
println(isvalid(String("a")))
println(isvalid(SubString(String(UInt8[0xfe, 0x80]), 1, 2)))

Output:

Example 2:

Python

# Julia program to illustrate 
# the use of isvalid() method
 
# Getting true if the specified value
# is valid for its type else returns false.
println(isvalid(Char, 0xd800))
println(isvalid(String, SubString("GeeksforGeeks", 1, 5)))
println(isvalid(Char, 'a'))

Output:
