Fxp() [3/4]

SRL::Math::Types::Fxp::Fxp ( const int16_t & value )

inlineconstexpr

Constructor for Fxp class from a 16-bit signed integer.

Parameters

value

The integer value to convert to fixed-point.

This is the primary runtime constructor for integer values. For runtime conversion from other numeric types, use Convert():

// Convert with compile-time range validation
Fxp a = Fxp::Convert(someValue);     // Warns at compile-time if value exceeds int16_t range

Note

Converts to 16.16 fixed-point format (e.g., 10 becomes 10.0).

Warning

For advanced users who understand the risks of precision loss or overflow, manual casting is allowed. However, use the Convert function for safer conversions.

// Manual casting (advanced users only)
Fxp b = static_cast<int32_t>(someValue << 16); // No warnings, but risks overflow
