compute values of software float parameters
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:
evalf(ln(MAX_FLOAT)) - 1 ULP
Maximum setting of Digits
The largest integer b such that for a floating-point
number x, xr is computed by the kernel (for larger
exponents, xr is computed by the library routine
ULP = "Unit in the Last Place", and for LN_MAX_FLOAT this is computed using Digits = 10.
Note: The values in these examples are the values for the machine on which this help page was generated.
