iDevOS CALC "MAX" Command

Get the maximum value from a set of variables or an array of variables.

Description

CALC( y, a, b, "MAX" );     // y = max(a, b) = maximum of a, b
CALC( y, a, b, c, "MAX" );  // y = max(a, b, c) = maximum of a, b, c
CALC( y, array, "MAX" );    // y = max(array) = maximum value in array

If the parameters passed to this command are two or three individual variables (a, b, c) then this command returns the maximum value y of these variables. If an array is passed to this command then the returned value y is the maximum value found in the array.

See "MIN" to get the minimum value.

  CALC(d, 100, -69, 5, "MAX"); // d = 100

Example 2

VAR(arr, 0, S8, 6); // create array of size 6
VAR(res, 0, S8);    // result

// Initialise array: arr = { 5, -12, 0, 90, -15, 0 }

LOAD(arr.1, -12);
LOAD(arr.3, 90);
LOAD(arr.4, -15);
