iDevOS CALC "MIN" Command

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

Description

CALC( y, a, b, "MIN" );     // y = min(a, b) = minimum of a, b
CALC( y, a, b, c, "MIN" );  // y = min(a, b, c) = minimum of a, b, c
CALC( y, array, "MIN" );    // y = min(array) = minimum value in array

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

See "MAX" to get the maximum value.

Examples

Example 1

  VAR(d, 0, S32);
  
  CALC(d, 10, 20, "MIN");      // d = 10
  CALC(d, 100, -69, 5, "MIN"); // d = -69

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.0, 5);
LOAD(arr.1, -12);
LOAD(arr.3, 90);
LOAD(arr.4, -15);

CALC(res, arr, "MIN"); // res = -15
