Summary: This patch fixes incorrect truncation when the input wider value is exactly 2^dstBits. For that value, the overflow to infinity is not correctly handled. The fix is to replace a strict '>' with '>='. Currently, __truncdfsf2(340282366900000000000000000000000000000.0) returns infinity __truncdfsf2(340282366920938463463374607431768211456.0) returns 0 __truncdfsf2(400000000000000000000000000000000000000.0) returns infinity Likewise, __truncdfhf2 and __truncsfhf2 (and consequently gnu_f2h_ieee) are discontinuous at 65536.0. This patch adds tests for all three cases, along with adding a missing header include to fp_test.h.
