RangeError:新Float32Array时Float32Array的字节长度应为4的倍数

RangeError: When creating a new Float32Array, the byte length of Float32Array should be a multiple of 4.

Explanation: The RangeError is a type of error that occurs when a value is not within the range or set of allowed values. In this case, the error is specifically related to creating a new Float32Array object in JavaScript.

Float32Array is a typed array in JavaScript that represents an array of 32-bit floating-point numbers. When creating a new Float32Array, the byte length specified should be a multiple of 4. This is because each floating-point number in the array occupies 4 bytes of memory.

If the byte length provided is not a multiple of 4, the RangeError is thrown to indicate that the length is invalid.

To resolve this error, you need to ensure that the byte length passed to the Float32Array constructor is a multiple of 4.

Example:

const byteLength = 12; // Invalid byte length, not a multiple of 4
try {
  const floatArray = new Float32Array(byteLength);
} catch (error) {
  console.error(error); // RangeError: When creating a new Float32Array, the byte length of Float32Array should be a multiple of 4.
}

const validByteLength = 16; // Valid byte length, a multiple of 4
const floatArray = new Float32Array(validByteLength);
console.log(floatArray); // Float32Array(4) [0, 0, 0, 0]
