To convert  a  of type S to  x  of type T, you can write        conv(x, a);     or        x = to_T(a);      Note that when T is 'unsigned int/long', the functional     forms are 'to_uint' and 'to_ulong'.  [2] All conversions from ZZ to signed or unsigned int or long compute      the result modulo 2^n, where n is the number of bits of      the destination type.  [2] All floating point to integral conversions compute the floor     function *exactly*.  [3] The ZZ to double conversion routine is very precise:     the result is the nearest double, breaking ties using the      "round to even" rule.  Overflow results in +/- Infinity.     All this assumes the underlying floating point adheres to     the IEEE standard.  [4] All conversions to RR round to the current working precision.  [5] All conversions from long or ZZ to one of "mod p" types        ZZ_p, ZZ_pX, ZZ_pE, ZZ_pEX,        zz_p, zz_pX, zz_pE, zz_pEX,        GF2, GF2X, GF2E, GF2EX     yield the the residue class modulo p.  [6] All polynomial to polynomial conversions apply coefficient-wise     conversion.  [7] All vector/matrix to vector/matrix conversions apply element-wise     conversion.  [8] The GF2X/ZZ_pX/zz_pX to GF2E/ZZ_pE/zz_pE conversions reduce     the given polynomial modulo the current modulus.  [9] All conversions from the type  const char*  apply the same algorithm     as is used for reading from an I/O stream, so         ZZ x = to_ZZ("999999999999999999");     initializes the ZZ x to the integer 999999999999999999. [10] The conversions to vec_ZZ from vec_ZZ_p and vec_zz_p copy the     standard non-negative residues; likewise for the conversions     to ZZX from ZZ_pX and zz_pX.
