Floating-point is a Data representation of a number

Floating-point Ldapwiki refers you to Wikipedia: Floating-point_arithmetic#Floating-point_numbers

IEEE standardized the computer representation for binary Floating-point numbers in IEEE 754 (a.k.a. IEC 60559) in 1985 and was revised in 2008 which is used by almost all modern computers. IBM mainframes support IBM's own hexadecimal Floating-point format and IEEE 754-2008 decimal Floating-point in addition to the IEEE 754 binary format. The Cray T90 series had an IEEE version, but the SV1 still uses Cray Floating-point format.
