 ## Remarks
 
-Each function converts the input string *strSource* to a **`double`**. The **strtod** function converts *strSource* to a double-precision value. **strtod** stops reading the string *strSource* at the first character it cannot recognize as part of a number. This character may be the terminating null character. **wcstod** is a wide-character version of **strtod**; its *strSource* argument is a wide-character string. These functions behave identically otherwise.

 The UCRT versions of these functions don't support conversion of Fortran-style (**d** or **D**) exponent letters. This non-standard extension was supported by earlier versions of the CRT, and may be a breaking change for your code. The UCRT versions support hexadecimal strings and round-tripping of INF and NAN values, which weren't supported in earlier versions. This can also cause breaking changes in your code. For example, the string "0x1a" would be interpreted by **strtod** as 0.0 in previous versions, but as 26.0 in the UCRT version.
