    NAME

    exp2, exp2f, exp2l - base-2 exponential function
     
    

    SYNOPSIS

    #include <math.h>
    
    double exp2(double x);
    
    float exp2f(float x);
    long double exp2l(long double x);

    Link with -lm.

    Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

    exp2(), exp2f(), exp2l(): _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE; or cc -std=c99  

    DESCRIPTION

    The exp2() function returns the value of 2 raised to the power of x.  

    RETURN VALUE

    On success, these functions return the base-2 exponential value of x.

    For various special cases, including the handling of infinity and NaN, as well as overflows and underflows, see exp(3).  

    ERRORS

    See math_error(7) for information on how to determine whether an error has occurred when calling these functions.

    For a discussion of the errors that can occur for these functions, see exp(3).  

    VERSIONS

    These functions first appeared in glibc in version 2.1.  

    CONFORMING TO

    C99, POSIX.1-2001. The variant returning double also conforms to SVr4, 4.3BSD, C89.
