Hi,

godot does only have one int and one float type.

The int then has 2 ^ 63 max value + 1 bit for +/- sign

The float max value is much higher but looses precission due to the exponent

**int**

Short for “integer”, it stores whole numbers (positive and negative). It is stored as a 64-bit value, equivalent to “int64_t” in C++.

**float**

Stores real numbers, including decimals, using floating-point values. It is stored as a 64-bit value, equivalent to “double” in C++. Note: Currently, data structures such as Vector2, Vector3, and PoolRealArray store 32-bit single-precision “float” values.

They should to create some numerical constants. I don’t want that my games become broken when they decide to change that limits

So the answer is that it is not possible to get max/min value for int or float in godot?

The only way is calculate it manually by converting bit number with all bits set to 1?
