NumberArray Class

The NumberArray class contains static methods that act on arrays of numbers.

Methods

Name Description
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.
