Hpmbcalc can perform some statistical tests on an operand to help evaluate its randomicity. Simply enter the number to be checked in a Multibyte Hex Edit Box. Hpmbcalc will perform the following checks and display the results:

• Number of bytes: the byte length of the number.
• Number of bits: the total bit length of the number.
• Number of bit 1: the number of bit 1 in the number.
• Number of bit 0: the number of bit 0 in the number.
• Longest run of bit 1: the length in bits of the longest uninterrupted run of bit 1 in the number.
• Longest run of bit 0: the length in bits of the longest uninterrupted run of bit 0 in the number.
• Longest run of bits 10: the length in bit pairs of the longest uninterrupted run of bits 10 in the number. For example, the run "001010100" would be displayed as 3 (6 bits).
• Longest run of bits 01: the length in bit pairs of the longest uninterrupted run of bits 01 in the number under test. For example, the run "001010100" would be displayed as 3 (6 bits).
