strz_I1P Function

private elemental function strz_I1P(n, nz_pad) result(str)

Convert integer to string, prefixing with the right number of zeros.

 use penf
 print "(A)", strz(n=1_I1P)

 use penf
 print "(A)", strz(n=1_I1P, nz_pad=3)

Arguments

Type IntentOptional Attributes Name
integer(kind=I1P), intent(in) :: n

Integer to be converted.
integer(kind=I4P), intent(in), optional :: nz_pad

Number of zeros padding.

Return Value character(len=DI1P)

Returned string containing input number plus padding zeros.
