Intrinsic floating - point functions 內(nèi)部浮點函數(shù)
There are many floating - point functions in the process of fingerprint feature extraction and feature matching processes 指紋特征提取和特征匹配的過程中,存在大量的浮點運算。
The intrinsic floating - point functions do not perform any special checks on input values and so work in restricted ranges of input , and have different exception handling and boundary conditions than the library routines with the same name 內(nèi)部浮點函數(shù)不對輸入值執(zhí)行任何特殊檢查,因此只在有限的輸入范圍內(nèi)有效,且與同名庫例程具有不同的異常處理和邊界條件。
