(A3 0.50) It is recommended to use [[linearConversion]] instead of [[BIS_fnc_linearConversion]]:
<code>[[linearConversion]] [0,100,50,0,50,[[true]] ]; //same as [[0,100],50,[0,50]] [[call]] [[BIS_fnc_linearConversion]]</code>
As for clamp, true will disable new value out of its range while false won't:
<code>[[linearConversion]] [0,100,150,0,50,[[true]] ]; //return 50
[[linearConversion]] [0,100,150,0,50,[[false]] ]; //return 75
</code>

Description

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.
Arma 3
Faster alternative to BIS_fnc_linearConversion.
Groups:
Math

Syntax

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: Boolean - (Optional, default false) if true, resulting value cannot leave "to" range
Return Value:
Number - respectful value from "to" range

Examples

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);
