Diagnosing machine parameters.

The following attributes are available:

ibeta  - radix in which numbers are represented
it     - number of base-ibeta digits in the floating point mantissa M
machep - exponent of the smallest (most negative) power of ibeta that,
         added to 1.0,
         gives something different from 1.0
eps    - floating-point number beta**machep (floating point precision)
negep  - exponent of the smallest power of ibeta that, substracted
         from 1.0, gives something different from 1.0
epsneg - floating-point number beta**negep
iexp   - number of bits in the exponent (including its sign and bias)
minexp - smallest (most negative) power of ibeta consistent with there
         being no leading zeros in the mantissa
xmin   - floating point number beta**minexp (the smallest (in
         magnitude) usable floating value)
maxexp - smallest (positive) power of ibeta that causes overflow
xmax   - (1-epsneg)* beta**maxexp (the largest (in magnitude)
         usable floating value)
irnd   - in range(6), information on what kind of rounding is done
         in addition, and on how underflow is handled
ngrd   - number of 'guard digits' used when truncating the product
         of two mantissas to fit the representation

epsilon - same as eps
tiny    - same as xmin
huge    - same as xmax
precision   - int(-log10(eps))
resolution  - 10**(-precision)
