FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package bcmath

trademinator/bcmath

Framework-agnostic BCMath helpers and reusable precision utilities for PHP.

The package has no Laravel dependency. Laravel applications may construct a PrecisionPolicy from their own configuration, while standalone PHP applications can instantiate the same objects directly.

Requirements

Installation

Once the repository/package is published:

Public functions

Decimal precision

bcdec() returns the exact largest represented decimal count. It does not impose a minimum scale.

Scientific notation is expanded first, without converting string input to float:

PrecisionPolicy and PrecisionContext

Resolve precision once for a price/data slice, then pass the resolved scale through hot-path calculations instead of repeatedly recalculating decimal precision.

Default policy:

Standard deviation

The old Trademinator helper name stats_standard_deviation() is replaced by the BCMath-style bcstddev():

Logarithm

bclog10() returns a decimal string. It does not convert decimal string input to float.

Intentional package boundary

technical_scale() is not part of this package. It belongs to the Trademinator Technical layer because it is technical-indicator precision policy, not a missing generic BCMath primitive.

Likewise, this package contains no EXCHANGE_ROUND_DECIMALS constant and no framework configuration lookup. Precision is explicit through PrecisionPolicy, PrecisionContext, or a function's scale argument.

Laravel

No service provider is required. Use the package exactly as in plain PHP. If Laravel configuration should control precision, translate that configuration into a PrecisionPolicy in the application layer and pass the resolved context explicitly.
