Why Do SQL `float` and C# `float` Types Cause Casting Errors?

Why SQL Float and C# Float May Clash

When working with data between SQL and C#, it's crucial to understand the differences in data types, especially when dealing with floating-point numbers. In this case, the issue arises when trying to assign a SQL float value to a C# float variable, resulting in an InvalidCastExecption.

A SQL float, according to the documentation for SqlDbType, corresponds to a double-precision floating-point number in C#. However, C#'s float data type only supports single-precision floating-point numbers.

The solution is to cast the SQL float to a double, which is the corresponding data type in C#. Here's the corrected code:

_AccelLimit = (float)(double)exercise["DefaultAccelLimit"];

By explicitly casting the SQL float to a double, we ensure that the value is converted to the correct format before assigning it to the C# float variable. This resolves the InvalidCastExecption and ensures accurate data handling.
