mpfr_libmpfr_get_flt Method
Convert op to a float, using the rounding mode 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 float mpfr_get_flt(
	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: Single
The converted floating-point number.
Remarks

If op is NaN, some fixed NaN (either quiet or signaling) or the result of 0.0/0.0 is returned. If op is ±Inf, an infinity of the same sign or the result of ±1.0/0.0 is returned. If op is zero, the function returns a zero, trying to preserve its sign, if possible.

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_flt(op, mpfr_rnd_t.MPFR_RNDN) == -123.0);

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