Available APIs and floating-point implementations

The .NET System.Math APIs are available with double parameters. No sweat for the CPUs where the code usually runs. When we move to embedded systems that's a totally different story.

A few more details to properly set context:

  • double type: represents a double-precision 64-bit number with values ranging from negative 1.79769313486232e308 to positive 1.79769313486232e308. Precision ~15-17 digits. Size 8 bytes.
  • float type: represents a single-precision 32-bit number with values ranging from negative 3.402823e38 to positive 3.402823e38. Precision ~6-9 digits. Size 4 bytes.
  • Comparison of floating-point numeric types.

There are all sorts of variants and combinations on how to deal with FP and DP in the embedded world. From hardware support on the CPU to libraries that perform those calculations at the expense of more code and execution speed. .NET nanoFramework targets 32-bit MCUs, therefore support for 64-bits calculations requires extra code and processing.

Adding to the above, the extra precision provided by the double type is seldom required on typical embedded application use cases.

Considering all this and the ongoing quest to save flash space, despite System.Math API offering double type parameters, the type handling at the native code will depend on build options of the firmware. The default implementation works with float under the hood. There is a build option (DP_FLOATINGPOINT) to build the image with DP floating point, which should be used when 'that' extra precision is required.

In case this is relevant, the capability of dealing with double floating point is exposed through this property SystemInfo.FloatingPointSupport.
