Project Notes

Numeric Limits

Numeric limits information available in the C++ standard library.

Notes

The C standard library relies on macros to define numeric limits. The C++ library instead provides a class template for a standardized way to query properties of arithmetic types. The standard library makes available specializations for all arithmetic types.

Running the Example

See example.cpp for details. A makefile compiles and runs:

$ make
c++ -std=c++17 -Wall -O3    example.cpp   -o example
./example
## Numeric Limits
type  lowest()  min()   max()
----  --------  -----   -----
bool  0   0   1
uchar 0   0   255
int -2147483648 -2147483648 2147483647
float -3.40282e+38  1.17549e-38 3.40282e+38
double  -1.79769e+308 2.22507e-308  1.79769e+308

This page is a web-friendly rendering of my project notes shared in the LittleCodingKata GitHub repository.

LittleCodingKata is my collection of programming exercises, research and code toys broadly spanning things that relate to programming and software development (languages, frameworks and tools).

These range from the trivial to the complex and serious. Many are inspired by existing work and I'll note credits and references where applicable. The focus is quite scattered, as I variously work on things new and important in the moment, or go back to revisit things from the past.

This is primarily a personal collection for my own edification and learning, but anyone who stumbles by is welcome to borrow, steal or reference the work here. And if you spot errors or issues I'd really appreciate some feedback - create an issue, send me an email or even send a pull-request.
