round

Description

Returns a number rounded to the nearest integer or to a specified number of decimal places. For example, 1.5 becomes 2 and 8.1 becomes 8.

Syntax

Like many functions in DataPrime, round supports two notations, function and method notation. These interchangeable forms allow flexibility in how you structure expressions.

round(number: number, digits: number?): number

(number: number).round(digits: number?): number

Arguments

Example

Use case 1: Round averages for discrete counts

Compute the average number of online users and round to a whole number for clarity. Example: 569.5 becomes 570.

Use case 2: Round latency values for readability

When analyzing traces, average latency values may have long decimal places. Use round with 2 digits for cleaner results.
