Excel Math & Trig functions perform many of the common mathematical calculations, including basic arithmetic, conditional sums & products, exponents & logarithms, and the trigonometric ratios.
To change negative numbers to positive and leave positive numbers along (i.e. get absolute values) use the built-in ABS function. See illustration below: Formula =ABS(number) Explanation In the example shown the formula in C6 is: =ABS(B6) How this formula works The ABS function is fully automatic. All you need to do is supply a number …
To calculate required currency denominations, given a specific amount, you can build a currency calculation table as shown in the example. This solution uses the INT and SUMPRODUCT functions. Formula =INT((amount-SUMPRODUCT(denoms,counts))/currentdenom) Explanation In the example show, the formula in D5 is: =INT(($B5-SUMPRODUCT($C$4:C$4,$C5:C5))/D$4) How this formula works To start off, the formula in C5 is: =INT($B5/C$4) This formula divides …
To generate the ratio of two numbers to each other (e.g. 4:3, 16:9, etc.), you can do using division, the GCD function, and concatenation. In the formula of the formula below num1 represents the first number (the antecedent) and num2 represents the second number (the consequent). Formula =num1/GCD(num1,num2)&”:”&num2/GCD(num1,num2) Explanation In the example, the active cell contains this …
To convert a measurement in feet and inches to inches only (i.e. 4’5″ to 53) you can use a formula based on several functions, including LEFT, FIND, MID, and SUBSTITUTE. See illustration below: Formula =LEFT(B5,FIND(“‘”,B5)-1)*12+SUBSTITUTE (MID(B5,FIND(“‘”,B5)+1,LEN(B5)),””””,””) Explanation In the example shown, the formula in D5 is: =LEFT(B5,FIND(“‘”,B5)-1)*12+SUBSTITUTE (MID(B5,FIND(“‘”,B5)+1,LEN(B5)),””””,””) How this formula works In the first …
To convert a measurement in inches to inches and feet (i.e. 53 to 4′ 5″) you can use a formula based on the INT and MOD functions. See illustration below: Formula =INT(A1/12)&”‘ “&MOD(A1)&”””” Explanation In the example shown, the formula in D5 is: =INT(B5/12)&”‘ “&MOD(B5,12)&”””” How this formula works This formula converts a numeric value …
