C standard C89 had strtod but not strtof.
Strtof appears in the C99 standard.
The strtod returns a double type while strtof returns a float.
For most practical purposes you can substitute (float)strtod(...)
for strtof(...). There might be a difference in what happens on errors,
particularly if the converted result won't fit in a float variable, 
but this is not a likely problem if the author has chosen to use float 
rather than double. In most cases the cast (float) can be omitted.

I suggest you edit the application source to use strtod.
