- The PPRREECCIISSIIOONN intrinsic function returns the decimal precision of a
- number in the real number model. The real number model is described
- in the MMOODDEELLSS(3I) man page. This function accepts the following
- argument:
-
- _x Must be of type real or complex. It may be scalar or array
- valued.
-
- PPRREECCIISSIIOONN is an inquiry function. The name of this intrinsic cannot
- be passed as an argument.

- The result is a default integer scalar. The result has the value
- IINNTT((_p-1)*LLOOGG1100(_b))+_k, where _b and _p are as defined in the model and
- where _k is 1 if _b is an integral power of 10 and 0 otherwise.
