} <danielsh> incal, it just uses the C floor() function,

It's not an oversight.  The doc says:

Most functions take floating point arguments and return a floating point
value.  However, any necessary conversions from or to integer type will
be performed automatically by the shell.  Apart from atan with a second
argument and the abs, int and float functions, all functions behave as
noted in the manual page for the corresponding C function [...]

So ciel and floor return float precisely and intentionally because the
C functions do so.
