CDM Model - RoundToPrecision Function

Background

This release contains an enhancement for the RoundToPrecision function, as described in issue #2915.

What is being released?

This release updates the existing function cdm.base.math.RoundToPrecision to add a new boolean flag which specifies whether to remove trailing zeros.

func RoundToPrecision: <"Round a rate to the supplied precision, using the supplied rounding direction">
    inputs:
        value number (1..1) <"The original (unrounded) number.">
        precision int (1..1) <"The number of decimal digits of precision.">
        roundingMode RoundingDirectionEnum (1..1) <"The method of rounding (up/down/nearest).">
        removeTrailingZeros boolean (1..1) <"Flag to specify whether to remove trailing zeros.">
    output:
        roundedValue number (1..1) <"The value to the desired precision">

The following examples show the function behaviour:

  • RoundToPrecision(1023.123456789, 5, RoundingDirectionEnum -> NEAREST, false) = 1023.12346
  • RoundToPrecision(1023.123456789, 5, RoundingDirectionEnum -> NEAREST, true) = 1023.12346
  • RoundToPrecision(1023.12000, 5, RoundingDirectionEnum -> NEAREST, false) = 1023.12000
  • RoundToPrecision(1023.12000, 5, RoundingDirectionEnum -> NEAREST, true) = 1023.12
  • RoundToPrecision(1023, 5, RoundingDirectionEnum -> NEAREST, false) = 1023.00000
  • RoundToPrecision(1023, 5, RoundingDirectionEnum -> NEAREST, true) = 1023
  • RoundToPrecision(999999999, 4, RoundingDirectionEnum -> NEAREST, false) = 999999999.0000
  • RoundToPrecision(999999999, 4, RoundingDirectionEnum -> NEAREST, true) = 999999999
