It's a hexadecimal number, base 16.

0=0, 1=1 ... 9=9, A=10, B=11 ... F=15 when converting to decimal.

The left most digit is 16 times geater the right most digit, so ...

$7F = ( $7 * 16 ) + $F = ( 7 * 16 ) + 15 = 112 + 15 = 127 in decimal.

Hexadecimal and binary numbers are usually used instead of decimal numbers where the individual bits of a value are important ( LCD control commands and so on ) as it's easier to see which bits are set and clear without having to convert from decimal to binary. Converting hexadecimal to binary is quite easy once one gets familiar with it.
