16位整型数据(16-bit Integer) 16位整型数据使用16位二进制数来表示每个栅格单元的值。这种数据格式适合表示离散的分类数据或有限的数值范围,如地物类型、土地利用类型等。 16位整型数据采用16位二进制补码表示,范围通常是从-32768到32767,共有65536个不同的值。这种数据格式在栅格数据中存储相对简单,通常以整数形式...

using minifloat (8-bit float) to explain floating number concepts (scale, overflow, etc.). Floating arithmetic blocks don't have the 8-bit option, eg: addition, multiplication, subtraction, etc., and for me it would be very useful. Would it be possible to implement 8-bit float ...

BF16 is a custom 16-bit floating point format that differs from the standard IEEE 754 half-precision (FP16) format. It uses 1 bit for the sign, 8 bits for the exponent, and 7 bits for the mantissa (or significand). This configuration allows BF16 to have the same dynamic range as FP...
FP16 is a 16-bit floating point format defined by the IEEE 754 standard. It uses 1 bit for the sign, 5 bits for the exponent, and 10 bits for the mantissa (or significand). This format allows for a wide range of values while using less memory compared to single-precision (FP32) or...
