Fix C4305 double truncated to float warnings (backport #666)

[mergify]

🦟 Bug fix

Small fix, Windows warnings related to C4305 in a couple of tests.

Summary

C++ literals default to double, and Windows build it's complaining because EXPECT_FLOAT_EQ test macros are expecting the use of a float type. Changing the literals to use f, so they should be using float now.
