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.

Say given range is 0 to 1 and wanted range is 0 to 100 (percent calculation). Given value 0.55 then will be
linearConversion [0,1,0.55,0,100]; //55
but if given value is 1.1
linearConversion [0,1,1.1,0,100,false]; //110
or if clipping is true
linearConversion [0,1,1.1,0,100,true]; //100

Syntax

Syntax:

linearConversion [minFrom, maxFrom, value, minTo, maxTo, clip]

Parameters:

[minFrom, maxFrom, value, minTo, maxTo, clip]: Array

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): Boolean - if true, resulting value cannot leave "to" range. Default: false

Return Value:

Number - respectful value from "to" range

Examples

Example 1:

linearConversion [4, 8, 5, 0, 1, false];

Example 2:

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);

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