● Decimal and Hexadecimal table

(Hexadecimal number is shown with H.) In MIDI documentation, data values and addresses/sizes of system exclusive messages etc. are expressed as hexadecimal values for each 7 bits. The following table shows how these correspond to decimal numbers.

* A 7-bit byte can express data in the range of 128 steps. For data where greater precision

is required, we must use two or more bytes. For example, two hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of aa x 128 + bb.

* In the case of values which have a ± sign, 00H = -64, 40H = ±0, and 7FH = +63, so that the

decimal expression would be 64 less than the value given in the above chart. In the case of two types, 00 00H = -8192, 40 00H = ±0, and 7F 7FH = +8191.

* Data marked "nibbled" is expressed in hexadecimal in 4-bit units. A value expressed as a

2-byte nibble 0a 0bH has the value of a x 16 + b.

<Ex.1> What is 5AH in decimal system?

<Ex.2> What in decimal system is 12034H in hexadecimal of every 7 bit?

<Ex.3> What in decimal system is 0A 03 09 0D in nibble system?

<Ex. 4> What in nibble system is 1258 in decimal system?

5AH = 90 according to the above table.

12H = 18, 34H = 52 according to the above table. So 18 x 128 + 52 = 2356.

0AH = 10, 03H = 3, 09H = 9, 0DH = 13 according to the table. So ((10 x 16 + 3) x 16 + 9) x 16 + 13 = 41885.

________

16)1258

16) 78 ... 10

16) 4 ... 14 0 ... 4

0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0AH According to the table. So it is 00 04 0E 0AH.
