49 * into one file, internal functions are declared static. This should
50 * allow inclusion into libraries with less chance of namespace collisions.

52 * snprintf should be the only externally visible item.

54 * As of 7-31-97 FLOATING_POINT is NOT provided. The code is somewhat
55 * non-portable, so it is disabled.
