WebRounding and padding with trailing zeros are typical methods implemented on processors to deal with the precision of binary words. Fixed-Point Data Type Parameters The low limit, high limit, and default binary-point-only scaling for the supported fixed-point data types discussed in Binary-Point-Only Scaling are given in the following table. WebThe term ‘fixed point’ refers to the corresponding manner in which numbers are represented, with a fixed number of digits after, and sometimes before, the decimal point. With floating-point representation, the placement of the decimal point can ‘float’ relative to the significant digits of the number.

"WebBit-fields which are declared as int (not signed int or unsigned int) can be implemented by the compiler using either signed or unsigned types. This makes a difference when extracting a value and deciding whether to sign extend it. The Oracle Developer Studio compiler uses unsigned types for int bit-fields and the gcc compiler uses signed types. " - Fixed point types not implemented
