NumberArray Class
The NumberArray class contains static methods that act on arrays of numbers.
Methods
| Name | Description | |
|---|---|---|
| createArrayWithMaxStepSize(low: number, high: number, step: number): number[] Static | Return an array with indicated start and end points, maximum step size internally | |
| isAlmostEqual(dataA: number[] | Float64Array | undefined, dataB: number[] | Float64Array | undefined, tolerance: number): boolean Static | Return true if arrays have identical counts and entries equal within tolerance | |
| isCoordinateInArray(x: number, data: number[] | undefined): boolean Static | test if coordinate x appears (to tolerance by Geometry.isSameCoordinate) in this array of numbers |
|
| isExactEqual(dataA: any[] | Float64Array | undefined, dataB: any[] | Float64Array | undefined): boolean Static | Return true if arrays have identical counts and equal entries (using !== comparison) |
|
| maxAbsArray(values: number[]): number Static | Return the max absolute value in a array of numbers. | |
| maxAbsDiff(dataA: number[] | Float64Array, dataB: number[] | Float64Array): number Static | Return the max absolute difference between corresponding entries in two arrays of numbers * If sizes are mismatched, only the smaller length is tested. |
|
| maxAbsDiffFloat64(dataA: Float64Array, dataB: Float64Array): number Static | Return the max absolute difference between corresponding entries in two Float64Array * If sizes are mismatched, only the smaller length is tested. |
|
| maxAbsTwo(a1: number, a2: number): number Static | return the max absolute value of a pair of numbers | |
| preciseSum(data: number[]): number Static | return the sum of values in an array, The summation is done with correction terms which improves last-bit numeric accuracy. |
|
| sum(data: number[] | Float64Array): number Static | return the sum of numbers in an array. |
