Double float int.
If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument.
Returns the largest integer that is less than or equal to the argument.
Returns the smallest of the two arguments.
If the argument is integer then the result is integer.
If the argument value is less than zero but greater than 1 0 then.
If the argument value is already equal to a mathematical integer then the result is the same as the argument.
If the exponent of the result is between double min exponent and double max exponent the answer is calculated exactly.
