A clear and concise description of what the bug is, and what you expected to happen.
When inserting JavaScript number values into FLOAT32 columns using the Node.js Spanner client, the values seems not to be properly converted to 32-bit floating point precision before insertion. This results in unexpected values being stored in the database.
For example, inserting the FLOAT32 value 3.14 results in the following database state:
A clear and concise description WHY you expect this behavior, i.e., was it a recent change, there is documentation that points to this behavior, etc. **
The correct value should be inserted to the database.
