 # Forbidden values management

 Last update: 22.04.2026 

The following page presents you how Speos handles the forbidden values when they are defined in scripts.

Forbidden values correspond to values that do not meet the Speos standards.

## Out of Range Values

If a value set in the script is out of the standard range in which it should be, then the previous value is defined.

Example

```ironpython
material = SpeosSim.Material.Create() (reflectance =100)
material.SOPReflectance =50; //ok
material.SOPReflectance =150; // keeps the previous value since it should be lower than 100

```

## Decimal Values

If a value set in the script uses decimals whereas it only allows integer, then the value is rounded up or down to the nearest whole number.

Example

```ironpython
material = SpeosSim.Material.Create()
material.SOPReflectance =15,4; // set the value to 15 since it should be an integer

```
