EXP(3)			 BSD Library Functions Manual			EXP(3)

NAME
     exp, exp2, expm1 — exponential functions

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() function computes e**x, the base-e exponential of x.

     The exp2() function computes 2**x, the base-2 exponential of x.

     The expm1() function computes the base-e exponential of x , minus 1 accu‐
     rately even for very small values of x.

SPECIAL VALUES
     exp(�0) and exp2(�0) return 1.

     exp(-infinity) and exp2(-infinity) return +0.

     exp(+infinity) and exp2(+infinity) return +infinity.

     expm1(�0) returns �0.

     expm1(-infinity) returns -1.

     expm1(+infinity) returns +infinity.

     For all these functions, a range error occurs if the magnitude of x is
     too large.

SEE ALSO
     math(3), infnan(3)

STANDARDS
     The exp() , expf() , exp2() , exp2f() , expm1() , and expm1f() functions
     conform to ISO/IEC 9899:1999(E).
