Julia | signbit() function

signbit() function is a library function in Julia programming language, it is used to check whether sign bit of number is ON or OFF, it returns true if the number is negative, otherwise, false.

Syntax:

    signbit(val)

Parameter(s):

• val – represents a signed integer/value, whose sign bit to be checked.

Return value:

The return type of this method is Bool, it returns true if the number is negative, otherwise, false.

Example:

    Input:
    val = 0
    Output:
    signbit(val): false

    Input:
    val = -10
    Output:
    signbit(val): true

    Input:
    val = 10
    signbit(val): false

Program:

# signbit() Function with Example in Julia

val = 0
println("val: ", val)
println("signbit(val): ", signbit(val))

val = 10
println("val: ", val)
println("signbit(val): ", signbit(val))

val = -10
println("val: ", val)
println("signbit(val): ", signbit(val))

val = 10.23
println("val: ", val)
println("signbit(val): ", signbit(val))

val = -10.23
println("val: ", val)
println("signbit(val): ", signbit(val))

# printing the return type of signbit()
println("typeof(signbit(-10)): ", typeof(signbit(-10)))

Output

val: 0
signbit(val): false
val: 10
signbit(val): false
val: -10
signbit(val): true
val: 10.23
signbit(val): false
val: -10.23
signbit(val): true
typeof(signbit(-10)): Bool
