How many digits of precision in a float
WebIntroduction to MySQL FLOAT Data Type. FLOAT is a numeric data type in MySQL used to store single-precision floating-point numbers (4 bytes). In MySQL, the range of FLOAT is from -3.402823466E+38 to -1.175494351E-38, 0, and from 1.175494351E-38 to 3.402823466E+38. WebJun 9, 2016 · A common answer is that floats have a precision of about 7.22 digits. While this may be true for integers, where gaps align and are both of size one, it’s not true for floating point numbers (the fact that it gets you …

WebOf course, exactly how many this is depends on whether you're using single or double precision. This pattern keeps going until you get down to the smallest possible exponent. For numbers smaller than this, the increments are all the same.

The 32 available bits are split into 24 for the mantissa and 8 for the exponent. The 24 bits for the mantissa represent a decimal number. The whole floating point number will only have 24 bits that are significant (that are non-zero.)
