If all the calculations are going to be in the database, you can just use strings on the Go side. Andy > On Jan 7, 2018, at 6:44 AM, evan wrote: > > c# has a decimal type that i can map my numeric(12,2) column data type to, > but golang doesnt have a decimal type. > > i

Re: [go-nuts] Go Compiler How Work?!

No, the Go compiler doesn’t actually generate ASM. It generates machine code. So it doesn’t need the help of another compiler or assembler. Andy > On Dec 13, 2017, at 9:00 AM, Compiler wrote: > > i am undrestand compiler steps. > only have problem in code generation step. >

Re: [go-nuts] "html/dom" alternative to html/template for true separation of concerns?

The placeholders never show up in template output. If the data is missing, the placeholders normally just disappear; in some cases there might be an error, depending on exactly what type of “missing.” Andy > On Sep 14, 2017, at 8:14 AM, Karv Prime wrote: > > As it would get a l
