Returns the smallest value in the list of arguments. Text and logical values such as TRUE and FALSE are compared as well as numbers.
Syntax
MINA(value1,value2,...)
Value1, value2,... are 1 to 30 values for which you want to find the smallest value.
Remarks

You can specify arguments that are numbers, empty , logical values, or text representations of numbers. Arguments that are error values cause errors. If the calculation must not include text or logical values, use the MIN function instead.

Arguments that contain TRUE evaluate as 1; arguments that contain text or FALSE evaluate as 0 (zero).

If the arguments contain no values, MINA returns 0.
