Partial function call and currying. What is the difference?

Question

Scala

Partial call:

def f(m: Int, n: Int) = m*n
val f3 = f(3, _:Int)
var result = f3(4)

Currying:

def f(m: Int)(n: Int) = m*n
val f3 = f(3) _
var result = f3(4)

Is there a difference in syntax, or is there some fundamental difference?

Answer 1

While partial application transforms a function with N parameters into a function with Nk parameters by applying one or more arguments, currying decomposes the function into functions of one argument while maintaining the sequence of arguments.

Answer 2

there is a good explanation here
