FREXP(3)            UNIX Programmer's Manual             FREXP(3)

NAME
     frexp, ldexp, modf - split into mantissa and exponent

SYNOPSIS
     double frexp(value, eptr)
     double value;
     int *eptr;

     double ldexp(value, exp)
     double value;

     double modf(value, iptr)
     double value, *iptr;

DESCRIPTION
     _F_r_e_x_p returns the mantissa of a double _v_a_l_u_e as a double
     quantity, _x, of magnitude less than 1 and stores an integer
     _n such that _v_a_l_u_e = _x*2**_n indirectly through _e_p_t_r.

     _L_d_e_x_p returns the quantity _v_a_l_u_e*2**_e_x_p.

     _M_o_d_f returns the positive fractional part of _v_a_l_u_e and
     stores the integer part indirectly through _i_p_t_r.
