-/*****************************************************************
- * The following routines are coded directly from the algorithms
- * and coefficients given in "Software Manual for the Elementary
- * Functions" by William J. Cody, Jr. and William Waite, Prentice
- * Hall, 1980.

-/******************************************************************
- * Square Root
- *
- * Input:
- *   x - floating point value
- *
- * Output:
- *   square-root of x
- *
- * Description:
- *   This routine performs floating point square root.
- *
- *   The initial approximation is computed as
- *     y0 = 0.41731 + 0.59016 * f
- *   where f is a fraction such that x = f * 2^exp.
- *
- *   Three Newton iterations in the form of Heron's formula
- *   are then performed to obtain the final value:
- *     y[i] = (y[i-1] + f / y[i-1]) / 2, i = 1, 2, 3.
