mpfr_libmpfr_get_sj Method
Convert op to an intmax_t after rounding it with respect to rnd.

Namespace:  Math.Mpfr.Native
Assembly:  Math.Mpfr.Native (in Math.Mpfr.Native.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
Copy
public static intmax_t mpfr_get_sj(
	mpfr_t op,
	mpfr_rnd_t rnd
)

Parameters

op
Type: Math.Mpfr.Nativempfr_t
The operand floating-point number.
rnd
Type: Math.Mpfr.Nativempfr_rnd_t
The rounding direction.

Return Value

Type: intmax_t
The converted floating-point number.
Remarks

If op is NaN, 0 is returned and the erange flag is set. If op is too big for the return type, the function returns the maximum or the minimum of the corresponding C type, depending on the direction of the overflow; the erange flag is set too. When there is no such range error, if the return value differs from op, i.e., if op is not an integer, the inexact flag is set. See also mpfr_fits_slong_p, mpfr_fits_ulong_p, mpfr_fits_intmax_p and mpfr_fits_uintmax_p.

Examples
Copy
// Create, initialize, and set a new floating-point number to -123.0
mpfr_t op = new mpfr_t();
mpfr_lib.mpfr_init2(op, 64U);
Assert.IsTrue(mpfr_lib.mpfr_set_d(op, -123.0, mpfr_rnd_t.MPFR_RNDN) == 0);

// Assert that the value of op is -123.0.
Assert.IsTrue(mpfr_lib.mpfr_get_sj(op, mpfr_rnd_t.MPFR_RNDN) == -123);

// Release unmanaged memory allocated for x.
mpfr_lib.mpfr_clear(op);
