  Single precision is known as float in C, C++, C#, Java[1] , and Haskell, and as single in Pascal, Visual Basic, and MATLAB. However, float in Python and single in versions of Octave prior to 3.2 refer to double precision numbers. Floating point precisions IEEE 754: 16-bit: Half (binary16) 32-bit: Single (binary32), decimal32
