C99 for code examples demonstrating access and use of IEEE 754 features
Floating-point arithmetic, for history, design rationale and example usage of IEEE 754 features
Fixed-point arithmetic, for an alternative approach at computation with rational numbers (especially beneficial when the exponent range is known, fixed, or bound at compile time)
IBM System z9, the first CPU to implement IEEE 754-2008 decimal arithmetic (using hardware microcode)
IBM z10, IBM z196, IBM zEC12, and IBM z13, CPUs that implement IEEE 754-2008 decimal arithmetic fully in hardware
ISO/IEC 10967, language-independent arithmetic (LIA)
Minifloat, low-precision binary floating-point formats following IEEE 754 principles
POWER6, POWER7, and POWER8 CPUs that implement IEEE 754-2008 decimal arithmetic fully in hardware
strictfp, an obsolete keyword in the Java programming language that previously restricted arithmetic to IEEE 754 single and double precision to ensure reproducibility across common hardware platforms (as of Java 17, this behavior is required)
Table-maker's dilemma for more about the correct rounding of functions
Standard Apple Numerics Environment
Tapered floating point
Posit, an alternative number format
