| intstr | integer-to-string function |
| Syntax | intstr ( i : int [ , width : int [ , base : int ] ] ) : string
| ||
| Description | The intstr function is used to convert an integer to a string. The string is equivalent to i, padded on the left with blanks as necessary to a length of width, written in the given number base. For example, intstr (14, 4, 10)="bb14" where b represents a blank. The width and base parameters are both optional. If they are omitted, the string is made just long enough to hold the value, and the number base is 10. For example, intstr (14, 4) = "bb14" and intstr (23 ) = "23". The width parameter must be non-negative. If width is not large enough to represent the value of i, the length is automatically increased as needed. The string returned by intstr is of the form:
where {blank} means zero or more blanks, [-] means an optional minus sign, and digit{digit} means one or more digits. The leftmost digit is either non-zero or else a single zero digit. In other words, leading zeros are suppressed. The letters A, B, C … are used to represent the digit values 10, 11, 12, … The base must be in the range 2 to 36 (36 because there are ten digits and 26 letters). For example, intstr (255, 0, 16) = "FF". The intstr function is the inverse of strint, so for any integer i,
strint ( intstr (i)) = i. | ||
