Return the digit value of `character` in `base`, or ‐1 if invalid.

== Synopsis

Declared in `<bdlb_numericparseutil.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
static
int
characterToDigit(
    char character,
    int base);
----

== Description

Determine whether the specified `character` represents a digit in the specified `base`; return the numeric equivalent if so, and ‐1 otherwise. The behavior is undefined if either `character` or `base` is 0 and unless `2 <= base` and `base <= 36` (i.e., bases where digits are representable by characters in the range [`0`‐`9`], [`a`‐`z`], or [`A`‐`Z`]).

== Return Value

digit value in `[0 .. base)]`, or ‐1 if `character` is not a valid digit in `base`

== Parameters
