Random Numbers in a Set Format
Open the page for the format you need, press once and read the number.
A plain random number is a whole number between two ends. Each page in this set draws a number in one written format and shows how that format works with one worked example. The percentage page draws a whole percent from 0% to 100%, or cuts 100% into 2 to 12 parts that add up exactly. The fraction page draws a proper, improper or mixed fraction and gives its simplest form, decimal and percent. The binary page draws a byte, writes it as eight bits and shows the same number in decimal and hex. The 7-digit page draws a number from 1,000,000 to 9,999,999, with quick ranges for 3 to 9 digits. The port page draws from the registered range, 1024 to 49151, and skips the numbers on its list of common services. The letter and number page draws label codes like B7 or KT482 in your own pattern, up to 1,000 without repeats.
