Carpet and vinyl are available at 10cm increments Below is how the calculation works for carpet, the vinyl section works in pretty much the same way in field #776 carpet length (field #632) is divided by 10 and rounded up so for a length of 565 cm we get 56.5 This calculation is rounded up so the resultant figure is 57 In field #765 the new calculate length (field # 766) is multiplied by 10 to round up to the nearest 10 so 570 This then is the carpet length in cm By multiplying this length by field #775 (the width expressed as cm) we get the number of sq cm. Dividing by 1000 expresses this in metres square, which we then multiply with the product price
