EXP2(3) Linux Programmer's Manual EXP2(3) 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 || _POSIX_C_SOURCE >= 200112L; 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.
