gmp_libmpf_random2 Method |
Generate a random float of at most max_size limbs, with long strings of zeros and ones in the binary representation.
Namespace:
Math.Gmp.Native
Assembly:
Math.Gmp.Native (in Math.Gmp.Native.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax public static void mpf_random2(
mpf_t rop,
mp_size_t max_size,
mp_exp_t exp
)
Public Shared Sub mpf_random2 (
rop As mpf_t,
max_size As mp_size_t,
exp As mp_exp_t
)
public:
static void mpf_random2(
mpf_t^ rop,
mp_size_t max_size,
mp_exp_t exp
)
static member mpf_random2 :
rop : mpf_t *
max_size : mp_size_t *
exp : mp_exp_t -> unit
Parameters
- rop
- Type: Math.Gmp.Nativempf_t
The result float. - max_size
- Type: Math.Gmp.Nativemp_size_t
The maximum number of limbs. - exp
- Type: Math.Gmp.Nativemp_exp_t
The range of the random exponent.
Remarks
The exponent of the number is in the interval -exp to exp (in limbs).
This function is useful for testing functions and algorithms, since these kind of random numbers have proven to be more
likely to trigger corner-case bugs.
Negative random numbers are generated when max_size is negative.
Examples
mpf_t rop = new mpf_t();
gmp_lib.mpf_init(rop);
gmp_lib.mpf_random2(rop, 10, 5);
gmp_lib.mpf_clear(rop);
Dim rop As New mpf_t()
gmp_lib.mpf_init(rop)
gmp_lib.mpf_random2(rop, 10, 5)
gmp_lib.mpf_clear(rop)
