WebNov 18, 2024 · Is float always 32-bit? The ‘int pointer’ size can be changed to 64 bits on 64 bits machines, since the memory address size is 64 bits. That means your ‘argument’ isn’t valid. A float is then still a float too: usually we say it is 32 bits, but everyone is free to deviate from it. What is the range of float?-38 to 3.4E+38 Floating ... WebHowever, since float has a precision of up to only 7 digits, it shows garbage values after its precision is exceeded. Our double variable shows the correct number because it has a precision of 15 digits, while the number itself consists of 13 digits. As an alternative, we can specify different precisions for different variables while printing them. china construction building aluminum panel
