Returns the smallest integer greater than or equal to an `f32`.

The since() method of Temporal.ZonedDateTime instances returns a new Temporal.Duration object representing the duration from another date-time (in a form convertible by Temporal.ZonedDateTime.from()) to this date-time. The duration is positive if the other date-time is before this date-time, and negative if after.

Float division that allows optimizations based on algebraic rules. May assume inputs are finite.

Returns the largest integer less than or equal to an `f32`.

The monthCode accessor property of Temporal.PlainDateTime instances returns a calendar-specific string representing the month of this date. It is calendar-dependent.

The eraYear accessor property of Temporal.ZonedDateTime instances returns a non-negative integer representing the year of this date within the era, or undefined if the calendar does not use eras (e.g., ISO 8601). The year index usually starts from 1 (more common) or 0, and years in an era can decrease with time (e.g., Gregorian BCE). era and eraYear together uniquely identify a year in a calendar, in the same way that year does. It is calendar-dependent.

Returns the base 10 logarithm of an `f128`.

Returns the base 10 logarithm of an `f64`.

The toPlainDateTime() method of Temporal.PlainDate instances returns a new Temporal.PlainDateTime object representing this date and a supplied time in the same calendar system.

Float division that allows optimizations based on algebraic rules.
