A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented as 1230 with an implicit scaling factor of 1000 (with "minus 3" implied decimal fraction digits, that is, with … WebThe FIXED function syntax has the following arguments: Number Required. The number you want to round and convert to text. Decimals Optional. The number of digits to the right of the decimal point. No_commas Optional. A logical value that, if TRUE, prevents FIXED from including commas in the returned text. Remarks
