Problem with float in TurboC 1.0?

[Larry Gilbert]

I am trying to get some third-party C source to compile under TurboC version
1.0 [sic].  It does a lot of passing of type 'float' parameters, and I'm
finding that a lot of times, when there is an attempt to pass a float
parameter to a function, it mysteriously gets reset to 0.0.  Can anyone give
me a clue as to what is going on, or what I should look out for?  Thanks.
