AND(b0,b1,…)
b0: logical value
b1: logical value
AND calculates the logical conjunction of its arguments b0,b1,...
If an argument is numerical, zero is considered FALSE and anything else TRUE. Strings and empty values are ignored. If no logical values are provided, then the error #VALUE! is returned. This function is strict: if any argument is an error, the result will be the first such error.
This function is Excel compatible.
