Parámetros
1	entero	Entero a aplicar la función divisor
2	exp	Exponente a elevar cada divisor. Si el valor es 0 o no se especifica este parámetro y <entero> es EnteroGrande, se obtiene la función tau, que devuelve el nº de divisores Si el valor es 1 o no se especifica este parámetro y <entero> es RealDoble, se obtiene la función sigma, que devuelve la suma de divisores	0\|1

nº de divisores, función tau τ=σ₀:

fdiv(10b)

RealDoble: 4

fdiv(10b)=dim(div(10))

Booleano: verdadero

suma de divisores, función sigma σ=σ₁:

fdiv(10)

RealDoble: 18

fdiv(10)=sum(div(10))

Booleano: verdadero

σ₂:

fdiv(10,2)

RealDoble: 130

fdiv(10,-1)

RealDoble: 1.8
