Validate the complete numeric string before normalizing.

Number.parseFloat(newValue) accepts numeric prefixes. "1e", "1e-", "12abc", and "1.2.3" are normalized to "1", "1", "12", and "1.2", so valid prefix text is lost. Valid Infinity text is also preserved through this path.

Use a Number.isFinite() parse result for valid strings and preserve intermediate empty, negative, or decimal-typing states separately. Add regression tests for "1e", "12abc", "Infinity", and -34.1147648.

Proposed fix 
-    const parsed = Number.parseFloat(newValue);
+    const parsed = Number(newValue);
+    const isCompleteNumber =
+      Number.isFinite(parsed) &&
+      /^[+-]?(?:\d+(?:\.\d*)?|\.\d+)(?:[eE][+-]?\d+)?$/.test(newValue);
     controllerField.onChange(
-      Number.isNaN(parsed) ? newValue : parsed.toString(),
+      isCompleteNumber ? parsed.toString() : newValue,
     );

Test both ends of each coordinate range.

These cases test only latitude values above 90 and longitude values below -180. A schema that accepts latitude below -90 or longitude above 180 still passes this suite. Add rejection tests for -91 and 181. Add acceptance tests for -90, 90, -180, and 180 if the documented bounds are inclusive.

Count decimal places across exponential notation.

Number.prototype.toString() can produce exponential form for small coordinates. split(".") then misses the exponent, so values like 1.2e-7 pass as only one decimal place when they represent eight. Handle the exponent explicitly or validate the original string before coercion.

Map empty coordinates to undefined before numeric coercion.

z.coerce.number() treats "" as 0 before .optional(), so clearing a latitude or longitude field can pass a defined zero coordinate to submit and later send a fixed position with that coordinate cleared to 0. Normalize blank strings to undefined before coercion, or update the form output contract and add tests for clearing one coordinate and both coordinates.
