+* -   The `cmach` parameter is a string which specifies the double-precision machine parameter to be returned. The function recognizes the following characters:
+*
+*     -   `'E'`/`'e'`: (eps) relative machine precision.
+*     -   `'S'`/`'s'`: (sfmin) safe minimum such that `1/sfmin` does not overflow.
+*     -   `'B'`/`'b'`: (base) base of the machine (also known as the floating-point radix).
+*     -   `'P'`/`'p'`: (prec) `eps*base`.
+*     -   `'N'`/`'n'`: (t) number of (base) digits in the mantissa.
+*     -   `'R'`/`'r'`: (rnd) `1.0` when rounding occurs in addition and `0.0` otherwise.
+*     -   `'M'`/`'m'`: (emin) minimum exponent before (gradual) underflow.
+*     -   `'U'`/`'u'`: (rmin) underflow threshold.
+*     -   `'L'`/`'l'`: (emax) largest exponent before overflow.
+*     -   `'O'`/`'o'`: (rmax) overflow threshold.
