Introduction

In this tutorial we learn how to install rubygem-bigdecimal on CentOS 8.

What is rubygem-bigdecimal

Ruby provides built-in support for arbitrary precision integer arithmetic. For example 4213 -> 1265437718438866624512 BigDecimal provides similar support for very large or very accurate floating point numbers. Decimal arithmetic is also useful for general calculation, because it provides the correct answers people expect–whereas normal binary floating point arithmetic often introduces subtle errors because of the conversion between base 10 and base 2. rubygem-bigdecimal 1.3.4 107.module_el8.4.0+847+ee687b6c x86_64 97 k ruby-2.5.9-107.module_el8.4.0+847+ee687b6c.src.rpm appstream BigDecimal provides arbitrary-precision floating point decimal arithmetic http Ruby or BSD Ruby provides built-in support for arbitrary precision integer arithmetic.
