The Maple_floats(x) function computes the values of various parameters and constants associated with the arbitrary precision floating-point computation environment. This routine also computes the values of expressions involving these constants.

Maple_floats has option remember, so the constants are computed only once per session. Thus, for example, it is more efficient to compute

than to compute

if the computation is to be done more than once. In particular, it is more efficient if the computation is part of a procedure.

The constants known to Maple_floats are:

ULP = "Unit in the Last Place", and for LN_MAX_FLOAT this is computed using Digits = 10.
