This also something I wondered, it should be standard in the D
library. Implementing it can be done straight forward with
existing D language primitives, essentially a struct.
For those who don't know, decimal in C# is like a floating
point value but the exponent is a power of 10 (internally
total 16 bytes). This means that for "simple" mathematics
rational decimal values remains rational decimals values and
not some rounded value that would happen if you would use
normal floating point values. The decimal type is essential
for financial calculations.
I think D can more or less copy the C# solution.
Here's the implementation if anyone needs it:

Should be fairly straightforward to implement.
Thanks, but it is not full implementation of decimal, arithmetic
operator are missing.

Hello, I want read decimal type from sql db, do some
arithmetic operations inside D program and write it back to
DB. Result need to be close to result as if this operations
was performed in sql DB. Something like C# decimal.
Exists this kind of library ind D? (ideally `pure @safe @nogc
nothrow`).

Thanks, most of the packages are incomplete or too old (doesn't
compile), but this one https://code.dlang.org/packages/decimal
can by modified to work for my use.
