When is assembly faster than C?
...out floating point, they shine when it comes to precision as they give you 32 bits of precision with a predictable error (float only has 23 bit and it's harder to predict precision loss). i.e. uniform absolute precision over the entire range, instead of close-to-uniform relative precision (float).

How do I print the type of a variable in Rust?
...e, set the variable to a type which doesn't work:
let mut my_number: () = 32.90;
// let () = x; would work too

Objective-C implicit conversion loses integer precision 'NSUInteger' (aka 'unsigned long') to 'int'
...as unsigned long, and
unsigned long is a 64-bit unsigned integer.
int is a 32-bit integer.
So int is a "smaller" datatype than NSUInteger, therefore the compiler warning.
See also NSUInteger in the "Foundation Data Types Reference":
When building 32-bit applications, NSUInteger is a 32-bit un...

Change column type from string to float in Pandas
... if you wanted to save some memory and use a more compact dtype, like float32, or int8?
to_numeric() gives you the option to downcast to either 'integer', 'signed', 'unsigned', 'float'. Here's an example for a simple series s of integer type:
>>> s = pd.Series([1, 2, -7])
>>> s
