Is there a possibility to change celected text in V8 by my giving number?

I have over 1000 texts in default layer like (heights 46.34 and 47.57 and 56.21 and 59.99 so.on) but I need to change them 0.12 cm. Like this numbers must be like(heights 46.44 and 47.69 and 56.33 and 60.11 and so on.) I need to calculate to some of them 0.12, some other 0.08cm.
