gmp_libmpz_set_str Method |
Set the value of rop from str, a null-terminated C string in base base.
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 int mpz_set_str(
mpz_t rop,
char_ptr str,
int base
)
Public Shared Function mpz_set_str (
rop As mpz_t,
str As char_ptr,
base As Integer
) As Integer
public:
static int mpz_set_str(
mpz_t^ rop,
char_ptr str,
int base
)
static member mpz_set_str :
rop : mpz_t *
str : char_ptr *
base : int -> int
Parameters
- rop
- Type: Math.Gmp.Nativempz_t
The destination integer. - str
- Type: Math.Gmp.Nativechar_ptr
The source integer. - base
- Type: SystemInt32
The base.
Return Value
Type:
Int32This function returns 0 if the entire string is a valid number in base
base. Otherwise it returns −1.
Remarks
White space is allowed in the string, and is simply ignored.
The base may vary from 2 to 62, or if base is 0, then the leading characters are
used: 0x and 0X for hexadecimal, 0b and 0B for binary, 0 for octal,
or decimal otherwise.
For bases up to 36, case is ignored; upper-case and lower-case letters have the same value.
For bases 37 to 62, upper-case letter represent the usual 10..35 while lower-case
letter represent 36..61.
Examples
mpz_t x = new mpz_t();
gmp_lib.mpz_init(x);
char_ptr value = new char_ptr("12 345 678 909 876 543 211 234 567 890 987 654 321");
gmp_lib.mpz_set_str(x, value, 10);
char_ptr s = gmp_lib.mpz_get_str(char_ptr.Zero, 10, x);
Assert.IsTrue(s.ToString() == value.ToString().Replace(" ", ""));
gmp_lib.mpz_clear(x);
gmp_lib.free(value);
gmp_lib.free(s);
Dim x As New mpz_t()
