Default is bits, the digits= keyword argument its for decimal digits
instead.
Signature: pi.n(self, prec=None, digits=None, algorithm=None):
Docstring:
Return a numerical approximation this symbolic expression as either
a real or complex number with at least the requested number of bits
or digits of precision.
EXAMPLES:
sage: sin(x).subs(x=5).n()
-0.958924274663138
sage: sin(x).subs(x=5).n(100)
-0.95892427466313846889315440616
sage: sin(x).subs(x=5).n(digits=50)
-0.95892427466313846889315440615599397335246154396460
