doubletyyppi
Doubletyyppi is a term used in Finnish programming literature to refer to the double-precision floating-point data type, commonly known simply as double. It is defined by the IEEE 754 standard as a 64-bit binary floating-point representation. In most programming languages, the double type provides about 15 to 17 significant decimal digits of precision and supports a broad numeric range, from around 4.9e-324 (the smallest positive subnormal value) up to about 1.8e308 (the maximum finite value).
The typical memory layout consists of 1 sign bit, 11 exponent bits, and 52 fraction bits. This
Common uses include numerical simulations, data analysis, and algorithms requiring real-number arithmetic with high precision. For
In practice, the term doubletyyppi is a localized reference to the same underlying concept used in many
