Shrink large float to smaller float ?

[CinnamonMetal]

How can I shrink a large float value which represents a color to a float with a minimum of three decimal places although it still remains the same color in python ?

google > cut float decimal

float original = 4.48;

int tmp = original * 10; // 44.8 truncated to 44

float truncated = tmp / 10.0; // 4.4

When truncating a float which represents color how can I verify whether the two values are equally the same color ?
