MLGetReal()

FilledSmallSquare int MLGetReal(MLINK link, double *x) gets a floating-point number from the MathLink connection specified by link and stores it in x.

FilledSmallSquare If the data on the link corresponds to an integer, MLGetReal() will coerce it to a double before storing it in x.

FilledSmallSquare If the data on the link corresponds to a number outside the range that can be stored in a C double on your computer system, then MLGetReal() will fail, and return 0.

FilledSmallSquare You can get arbitrary-precision real numbers by first using RealDigits to generate lists of digits, then calling MLGetIntegerList().

FilledSmallSquare MLGetReal() is normally equivalent to MLGetDouble().

FilledSmallSquare See Section 2.13.4.
