WebThe float datatype in SGEMM has 7 decimal digits reserved for precision and the toal size is 32 bits . On the other hand, the double datatype used in DGEMM has a total size of 64 bits and is a standard: "IEEE 754 double-precision floating point number". SGEMM vs GEMM; The main difference is that GEMM is the generalized function.
