MATHEMATICA MATHLINK C FUNCTION

MLGetReal()

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

Details Details

If the data on the link corresponds to an integer, MLGetReal() will coerce it to a double before storing it in x.
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.
You can get arbitrary-precision real numbers by first using RealDigits to generate lists of digits, then calling MLGetIntegerList().
MLGetReal() is normally equivalent to MLGetDouble() and MLGetReal64().
