The software will remove all spaces from the text box. This web page supports number bases up to 62. Bases from 11 to 36 use case-insensitive letters A thru Z for digits greater than 9. Bases from 37 to 62 use uppercase letters for digits from 10 to 35 and lowercase letters for digits from 36 to 61. A negative number should be identified by one hyphen in front of the number. An input number can have up to 10000 base 10 digits to the left of the period and 10000 base 10 digits to the right of the period. Other bases have maximum accuracy levels given by "10000 * log(10) / log(base)". Integers will either be converted accurately, or an error message will be returned. If a fraction (designated by a period in the proper position) is entered, round-off error can occur.
