Math Query Functions

LogScale's math query functions provide a range of arithmetical and numerical functions.

Note

Math functions on ARM architecture may return different results in very high-precision calculationsc compared to Intel/AMD architectures.

`math:arctan2([as], x, y)`			Calculates the arc tangent of a value.
`math:ceil([as], field)`	`field`		Rounds field value to smallest integer that's larger than or equal to it.
`math:cos([as], field)`	`field`		Calculates the cosine of a field.
`math:cosh([as], field)`			Computes the hyperbolic cosine of a double field.
`math:deg2rad([as], field)`	`field`		Converts angles from degrees to radians.
