API

CreateAsNumbers(rows: number = 0): number

Return a maxtrix (array of array's) containing the values as integers of the rows in order from top to bottom.

rows

Type: number Default: 0

• Zero-based -- if you want to generate the first level you should pass in 0
• Greater than or equal to 0
• Less than 57 -- Row 57 and rows after will calculate an integer values greater than safe maximum integer. It is not wise to calculate futher with that value -- If the required rows is greater than or equal to 57, you should use CreateAsBigInt

CreateAsBigInt = (rows: number = 0): bigint

Return a maxtrix (array of array's) containing the values as bigint's of the rows in order from top to bottom.

rows

Type: number Default: 0

• Zero-based -- if you want to generate the first level you should pass in 0
