-/*							exp10.c
- *
- *	Base 10 exponential function
- *      (Common antilogarithm)
- *
- *
- *
- * SYNOPSIS:
- *
- * double x, y, exp10();
- *
- * y = exp10( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Returns 10 raised to the x power.
- *
- * Range reduction is accomplished by expressing the argument
- * as 10**x = 2**n 10**f, with |f| < 0.5 log10(2).
- * The Pade' form
- *
- *    1 + 2x P(x**2)/( Q(x**2) - P(x**2) )
- *
- * is used to approximate 10**f.
- *
- *
- *
- * ACCURACY:
- *
- *                      Relative error:
- * arithmetic   domain     # trials      peak         rms
- *    IEEE     -307,+307    30000       2.2e-16     5.5e-17
- * Test result from an earlier version (2.1):
- *    DEC       -38,+38     70000       3.1e-17     7.0e-18
- *
- * ERROR MESSAGES:
- *
- *   message         condition      value returned
- * exp10 underflow    x < -MAXL10        0.0
- * exp10 overflow     x > MAXL10       MAXNUM
- *
- * DEC arithmetic: MAXL10 = 38.230809449325611792.
- * IEEE arithmetic: MAXL10 = 308.2547155599167.
