Unverified50% confidenceFactExact time
2^31 is the boundary of a 32-bit signed integer; when the total number of matrix elements M*N reaches 2^31, linear indexing with int32 overflows (wraps around to a negative number), which may lead to incorrect results or illegal memory access.

UnverifiedFP32 uses 32 binary bits to represent a number (1 sign bit, 8 exponent bits, 23 mantissa bits) and can accurately represent approximately 7 significant decimal digits.73% similarUnverified32位有符号整数最大值为2,147,483,64769% similarUnverifiedSingle-precision floating-point (float, 32-bit) has only 23 mantissa bits, and can precisely represent integers in the range of approximately ±2^24.65% similarUnverifiedUsing double to accelerate 32-bit integer division is relatively safe, whereas 64-bit integer division (maximum value approximately 9.2×10^18) exceeds the range that double can represent exactly and requires caution.63% similarUnverifiedFor 32-bit integers exceeding 2²⁴, the mantissa precision of single-precision floating-point is insufficient to represent the value exactly, causing the exponent field to be underestimated.62% similar
