Thanks
eval ls ${exp} may be more efficient than using a new child sh,
such as ksh -c "ls $exp".
Radoulov, Much thanks for your help.

expm1f
EXP(3) BSD Library Functions Manual EXP(3) NAME
exp, expf, exp2, exp2f, expm1, expm1f, -- exponential functions LIBRARY
Math Library (libm, -lm) SYNOPSIS
#include <math.h> double exp(double x); float expf(float x); double exp2(double x); float exp2f(float x); double expm1(double x); float expm1f(float x); DESCRIPTION
The exp() and the expf() functions compute the base e exponential value of the given argument x. The exp2(), and exp2f() functions compute the base 2 exponential of the given argument x. The expm1() and the expm1f() functions computes the value exp(x)-1 accurately even for tiny argument x. RETURN VALUES
These functions will return the appropriate computation unless an error occurs or an argument is out of range. The functions exp() and expm1() detect if the computed value will overflow, set the global variable errno to ERANGE and cause a reserved operand fault on a VAX. SEE ALSO
math(3) STANDARDS
The exp() functions conform to ANSI X3.159-1989 (``ANSI C89''). The exp2(), exp2f(), expf(), expm1(), and expm1f() functions conform to ISO/IEC 9899:1999 (``ISO C99''). HISTORY
The exp() functions appeared in Version 6 AT&T UNIX. The expm1() function appeared in 4.3BSD. BSD
