Brick Math is a PHP library that provides arbitrary-precision arithmetic for integers, rational numbers, and decimal numbers. It is designed to overcome the limitations of PHP’s native number handling, especially for applications dealing with large numbers, financial calculations, or scientific computations. Brick Math complies with standards like IEEE 754 and avoids rounding errors inherent to floating-point arithmetic.

Brick\Money is a PHP library designed to provide precise and reliable handling of monetary values using arbitrary-precision arithmetic, ensuring accuracy in financial calculations of any scale. Built on top of the brick/math library, it avoids floating point errors by using exact decimal representations, making it suitable for applications where correctness is critical, such as accounting and financial services. The library supports ISO 4217 currency standards and includes comprehensive tools for working with currency units, conversions, and rounding strategies. ...

...For purposes of speed, OpenSSL, GMP, libsodium or mcrypt are used, if they're available, but they are not required. phpseclib is designed to be fully interoperable with standardized cryptography libraries and protocols. MIT-licensed pure-PHP implementations of SSH-2, SFTP, X.509, an arbitrary-precision integer arithmetic library, Ed25519 / Ed449 / Curve25519 / Curve449, ECDSA / ECDH (with support for 66 curves), RSA (PKCS#1 v2.2 compliant), DSA / DH, DES / 3DES / RC4 / Rijndael / AES / Blowfish / Twofish / Salsa20 / ChaCha20, GCM / Poly1305. The only requirement that phpseclib 3.0 has is that you must be using PHP 5.6+. ...

For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision, represented as strings. This project replicates this in JavaScript (bcadd, bccomp, bcdiv, bcmul, bcsub, etc)
