Excel offers a wide range of built-in math functions for calculations, data analysis, and more. Below is an overview categorized by type, highlighting key functions and their primary uses.
Basic Arithmetic Functions
– SUM: Adds up a range of numbers (e.g., =SUM(A1:A10)).
– AVERAGE: Calculates the average of numbers in a range (e.g., =AVERAGE(B1:B5)).
– COUNT: Counts the number of cells containing numbers (e.g., =COUNT(C1:C20)).
– MIN: Returns the smallest number in a range (e.g., =MIN(D1:D15)).
– MAX: Returns the largest number in a range (e.g., =MAX(E1:E10)).
– PRODUCT: Multiplies numbers together (e.g., =PRODUCT(F1:F3)).
Trigonometric and Advanced Math Functions
– SIN: Computes the sine of an angle in radians (e.g., =SIN(PI()/2)).
– COS: Computes the cosine of an angle in radians (e.g., =COS(0)).
– TAN: Computes the tangent of an angle in radians (e.g., =TAN(PI()/4)).
– SQRT: Returns the square root of a number (e.g., =SQRT(16)).
– POWER: Raises a number to a specified power (e.g., =POWER(2,3)).
– EXP: Returns e raised to the power of a number (e.g., =EXP(1)).
– LN: Calculates the natural logarithm of a number (e.g., =LN(2.718)).
Rounding and Absolute Value Functions
– ROUND: Rounds a number to a specified number of digits (e.g., =ROUND(3.14159,2)).
– CEILING: Rounds a number up to the nearest multiple (e.g., =CEILING(4.2,1)).
– FLOOR: Rounds a number down to the nearest multiple (e.g., =FLOOR(4.8,1)).
– ABS: Returns the absolute value of a number (e.g., =ABS(-5)).
Statistical Functions
– STDEV: Estimates standard deviation based on a sample (e.g., =STDEV(G1:G10)).
– VAR: Calculates variance for a sample (e.g., =VAR(H1:H15)).
– MEDIAN: Returns the median of a group of numbers (e.g., =MEDIAN(I1:I20)).
These functions can be combined with cell references, ranges, and other formulas for complex operations. For accurate results, ensure inputs are numeric and consider using absolute or relative references as needed. Always check for errors like #DIV/0! or #VALUE! when working with functions.
