MINA(number1,number2,...)
MINA returns the smallest value of the given arguments. Numbers, text and logical values are included in the calculation too. If the cell contains text or the argument evaluates to FALSE, it is counted as value zero (0). If the argument evaluates to TRUE, it is counted as one (1). Note that empty cells are not counted.
Let us assume that the cells A1, A2, ..., A5 contain numbers and strings 11.4, 17.3, "missing", 25.9, and 40.1. Then
MINA(A1:A5) equals 0.
