I came across this line in some code and can’t find the syntax defined anywhere:
*(float *)csCoord.nX = lImportHeight* .04f; /* magic number to scale font size */ If I remove the f from .04f then the compiler gives a warning about possible data loss due to a conversion from ‘double’ to ‘float’. I assume the f is doing some sort of typecasting.
Has anyone seen this before? Where is this defined in the C standard?
The trailing f indicates to the compiler that it is a float type literal, just like ” indicate a literal string and the L suffix indicates a long int.
The C++ spec for literals is the same.
