SUMIF
Adds the cells specified by a given criterion. This function is used to sum a range when you search for a certain value.
The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every regular expression metacharacter or operator with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in .
When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".
SUMIF(Range; Criterion [; SumRange])
Range is the range to which the criterion is to be applied.
SumRange is the range from which values are summed. If this parameter has not been indicated, the values found in the Range are summed.
SUMIF supports the reference concatenation operator (~) only in the Range parameter, and only if the optional SumRange parameter is not given.
To sum up only negative numbers: =SUMIF(A1:A10;"<0")
=SUMIF(A1:A10;">0";B1:B10) - sums values from the range B1:B10 only if the corresponding values in the range A1:A10 are >0.
See COUNTIF() for some more syntax examples that can be used with SUMIF().
SUMSQ
Calculates the sum of the squares of a set of numbers.
SUMSQ(Number 1 [; Number 2 [; … [; Number 255]]])
This function ignores any text or empty cell within a data range. If you suspect wrong results from this function, look for text in the data ranges. To highlight text contents in a data range, use the value highlighting feature.
