S-BASIC's double-precision real data type supports up to 14 digits,
thereby allowing calculation up to 15! without loss of precision
<syntaxhighlight lang="BASIC">
function factorial(n=real.double)=real.double
if n = 0 then n = 1 else n = n * factorial(n-1)
end = n
var i=integer
print "Factorial Calculator"
print " n n!"
print "----------------------"
for i=1 to 15
print using "## #,###,###,###,###";i;factorial(i)
next i
end
</syntaxhighlight>
An iterative rather than recursive approach works equally well, if that
is your preference.
<syntaxhighlight lang="BASIC">
function factorial(n=real.double)=real.double
var i, f = real.double
f = 1
for i = 1 to n
f = f * i
next i
end = f
</syntaxhighlight>
