wpa_cli signal level

Just a short question: in wpa_cli, after the SCAN command the 
SCAN_RESULTS lists the results. I'd be interested in the "meaning" of 
the "signal level" column. What is its range? 0-255?

Signal quality/level information on the same AP:
1) iwlist wlan0 scan: Quality=88/100  Signal level:-55 dBm
2) wpa_cli result: 201

My interpretation:
1) this is considered to be 88% (or not?);
2) if the range is 0-255, then this is 79%;

Am I doing something wrong? I'd like to print a scale from 0-100% 
according to signal level of the selected AP. How to get relevant 
results with wpa_cli?

Many thanks,
