numeric()

Prev Next

This function returns "true" if a can be interpreted as a numerical value.

IMPORTANT:

Empty values (no mapping, no fix value, without value assignment by a function) are not interpreted as numerical. Hidden values (i.e. non-empty numerical and alphanumerical values with set Empty Flag), however, are.
