My technology is currently 75.00 and I have well over 1000 infra, but I'm getting the following message when trying to purchase a nuke:

You currently have a technology level of 75.00 and need at least a technology level of
You currently have an infrastructure level of 1,728.17 and need at least an infrastructure level of 1000.
I've attached a screenshot showing this as well. As a programmer, it looks like either the condition check is using a > 75 instead of >= 75 or my technology is actually 74.99x and it's being rounded up to 75.00 for display. Either way, it looks odd.
