If latitude is not within the range –90 to 90, inclusive, this function wraps the value to be within the range when action is set to 'None' or 'Warning'. It does not wrap when action is set to 'Error'.

As noted above, the actual sea-level surface of Earth, even in the absence of the effects of waves, winds, currents, and tides, is not a simple mathematical …
The geoid is the shape that the ocean surface would take under the influence of the gravity of Earth, including gravitational attraction and Earth's rotation, if other influences such as winds and tides were absent. This surface is extended through the continents (such as with very narrow hypothetical canals). According to Gauss, who first described it, it is the "mathematical figure of the Earth", a s… WebGravity Anomaly Maps and The Geoid The Workings of GRACE Key Spacecraft Components The Future : The geoid is a hypothetical Earth …
