2.1. The “Built-In Replacement” Functions ¶

Each of these functions acts as a (potentially) faster drop-in replacement for the equivalent Python built-in function. Please perform timing tests on your platform with your data to determine if these functions will actually provide you with a speed-up.

2.1.1. `float()`¶

2.1.2. `int()`¶

2.1.3. `real()`¶

2.2. The “Error-Handling” Functions ¶

Each of these functions will quickly convert strings to numbers (and also numbers to numbers) with fast and convenient error handling. They are guaranteed to return results identical to the built-in float or int functions.

2.2.1. `try_real()`¶

2.2.2. `try_float()`¶

2.2.3. `try_int()`¶

2.2.4. `try_forceint()`¶

2.2.5. `try_array()`¶

2.3. The “Checking” Functions ¶

These functions return a Boolean value that indicates if the input can return a certain number type or not.

2.3.1. `check_real()`¶

2.3.2. `check_float()`¶

2.3.3. `check_int()`¶

2.3.4. `check_intlike()`¶

2.3.5. `query_type()`¶

2.4. Deprecated “Error-Handling” Functions ¶

These functions have a less flexible interface than try_* functions, but otherwise do the same thing. New code should prefer the try_* functions instead, but the below functions will never be removed.

2.4.1. `fast_real()`¶

2.4.2. `fast_float()`¶

2.4.3. `fast_int()`¶

2.4.4. `fast_forceint()`¶

2.5. Deprecated “Checking” Functions ¶

These functions have a less flexible interface than check_* functions, but otherwise do the same thing. New code should prefer the check_* functions instead, but the below functions will never be removed.

2.5.1. `isreal()`¶

2.5.2. `isfloat()`¶

2.5.3. `isint()`¶

2.5.4. `isintlike()`¶
