What am i doing wrong? Getting float number after putting value into text object?

Hello all!

I'm using Construct 3 for a while now and as a beginner i learned a lot. But i recently had a problem which i did not understand. So i made some screenshots and uploaded them on imgur.

Tl,dr: To make it short, i add 0.05 to a local static variable 'Pulse_Tick_Heart' and show them every 'Pulse_Tick_Heart'Seconds in an text object. I expected text shown like this:

1 > 1.05 > 1.10 > 1.15 > 1.2 ... and so on.

Somehow it does this:

1 > 1.05 > 1.10 > 1.15000000000001 > 1.20000000000001 > 1.25000000000002 ...

I just don't get why this happend? Used to calculate like this before and never got problems. Did i anything wrong? I'm so cunfused.

There's no reason to change it to a string. The text object will display the int by just having ""&Pulse_Tick_Heart
