This module, fnDecimalUtil64 contains procedures for working with decimal strings and the int64 data type.
Note
Unless stated otherwise, procedures of this module are pure procedures.
Uses
Functions
public pure function decInt64OrSmaller(firstString, secondString) result(int32Out)- Author
- Khang Hoang Nguyen
- Since
- 1.0.0.f
Compare two strings bases on the content of the strings reference to int64 values. If the strings are valid signed decimal integer strings that can be parsed to int64 values then they will be compared base on their int64 values. Otherwise, the strings will be compared base on the priority ranking order below.
Arguments
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| character(len=*), | intent(in) | :: | firstString | A string to be compared to the string | ||
| character(len=*), | intent(in) | :: | secondString | A string to be compared to the string |
Return Value integer(kind=k_int32)
Subroutines
public pure subroutine decToInt64(input, output, error, startpos, endpos)- Author

| integer(kind=k_int32), | intent(in), | optional | :: | startpos | An int32 value of the position(inclusive) of where to start parsing. | |
| integer(kind=k_int32), | intent(in), | optional | :: | endpos | An int32 value of the position(inclusive) of where to end parsing. |
