Description:: Converts given value from given "from" range to wanted "to" range. If clipping is set to true, the resulting value is guaranteed to be within "to" range no matter what.
Faster alternative to BIS_fnc_linearConversion.
Groups:: Math

Syntax:: linearConversion [minFrom, maxFrom, value, minTo, maxTo, clip]
Parameters:: minFrom: Number - start "from" range
: maxFrom: Number - end "from" range
: value: Number - given value from "from" range
: minTo: Number - start "to" range
: maxTo: Number - end "to" range
: clip (Optional, default false): Boolean - if true, resulting value cannot leave "to" range
Return Value:: Number - respectful value from "to" range

Example 1:: // Say given range is 0 to 1 and wanted range is 0 to 100 (percent calculation). Given value 0.55 then will be 55 linearConversion [0,1,0.55,0,100]; // but if given value is 1.1 it will return 110 linearConversion [0,1,1.1,0,100,false]; // or if clipping is true it will return 100 linearConversion [0,1,1.1,0,100,true];
Example 2:: linearConversion [4, 8, 5, 0, 1, false];
Example 3:: // Calculate days from 1/1/1970 fnc_daysFromEpoc = { private _year = param [0]; private _days = 0; for "_i" from 1970 to _year - 1 do { _days = _days + round linearConversion [0, 1, dateToNumber [_i, 12, 31, 23, 59], 0, 365, false]; }; _days + linearConversion [0, 1, dateToNumber _this, 0, 365, false]; }; hint str (date call fnc_daysFromEpoc);
