We can convert a string to float in Python using the float() function. This is a built-in function used to convert an object to a floating point number. Internally, the float() function calls specified object __float__() function.
Description. The atof() function converts a character string to a double-precision floating-point value. The input string is a sequence of characters that can be interpreted as a numeric value of the specified return type.
In the C Programming Language, the atof function converts a string to a floating-point number (double). The atof function skips all white-space characters at the beginning of the string, converts the subsequent characters as part of the number, and then stops when it encounters the first character that isn't a number.
The code you need looks something like this: int exponent = (int)log10(fabs(d)); double mantissa = d / pow(10, exponent); printf("%f X 10^%d\n", mantissa, exponent);
Double.Parse("1.234567E-06", System.Globalization.NumberStyles.Float);
Also consider using
Double.TryParse("1.234567E-06", System.Globalization.NumberStyles.Float, out MyFloat);
This will ensure that MyFloat is set to value 0 if, for whatever reason, the conversion could not be performed. Or you could wrap the Double.Parse() example in a Try..Catch block and set MyFloat to a value of your choosing when an exception is detected.
