    Command:

    ldexpl

    
    
    
    

    SYNOPSIS

           #include <math.h>
    
           double ldexp(double x, int exp);
           float ldexpf(float x, int exp);
           long double ldexpl(long double x, int exp);
    
           Link with -lm.
    
       Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
    
           ldexpf(), ldexpl():
               _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
               _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
               or cc -std=c99
    
    
    

    DESCRIPTION

           The  ldexp()  function  returns the result of multiplying the floating-
           point number x by 2 raised to the power exp.
    
    
    

    RETURN VALUE

           On success, these functions return x * (2^exp).
    
           If exp is zero, then x is returned.
    
           If x is a NaN, a NaN is returned.
    
           If x is positive infinity (negative infinity), positive infinity (nega-
           tive infinity) is returned.
    
           If the result underflows, a range error occurs, and zero is returned.
    
           If the result overflows, a range error occurs, and the functions return
           HUGE_VAL, HUGE_VALF, or HUGE_VALL, respectively, with a sign  the  same
           as x.
    
    
    

    ERRORS

           See  math_error(7) for information on how to determine whether an error
           has occurred when calling these functions.
    
           The following errors can occur:
    
           Range error, overflow
                  errno is set to ERANGE.  An  overflow  floating-point  exception
                  (FE_OVERFLOW) is raised.
    
           Range error, underflow
                  errno  is  set to ERANGE.  An underflow floating-point exception
                  (FE_UNDERFLOW) is raised.
