MathLink C Function


int MLPutReal128(MLINK link, mlextended_double d)
puts the extend-precision floating-point number d to the MathLink connection specified by link.
  • MLPutReal128() returns 0 in the event of an error, and a nonzero value otherwise.
  • Use MLError() to retrieve the error code if MLPutReal128() fails.
  • MLPutReal128() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

/* put the expression Sqrt[2.70001] to a link */

void f(MLINK lp)
    if(! MLPutFunction(lp, "Sqrt", 1))
        { /* unable to put Sqrt[] to lp */ }

    if(! MLPutReal128(lp, 2.70001))
        { /* unable to put 2.70001 to lp */ }

    if(! MLEndPacket(lp))
        { /* unable to put the end-of-packet sequence to lp */ }

    if(! MLFlush(lp))
        { /* unable to flush any output buffered in lp */ }
