110 | NAME: |
---|
111 | STRSCI (function) |
---|
112 | |
---|
113 | PURPOSE: |
---|
114 | Given a number, returns a string of that B |
---|
115 | number in scientific notation format ( e.g. A x 10 ) |
---|
116 | |
---|
117 | CATEGORY: |
---|
118 | String Utilities |
---|
119 | |
---|
120 | CALLING SEQUENCE: |
---|
121 | Result = STRSCI( DATA [,keywords] ) |
---|
122 | |
---|
123 | INPUTS: |
---|
124 | DATA -> A floating point or integer number to be |
---|
125 | converted into a power of 10. |
---|
126 | |
---|
127 | KEYWORD PARAMETERS: |
---|
128 | FORMAT -> The format specification used in the string |
---|
129 | conversion for the mantissa (i.e. the |
---|
130 | "A" of "A x 10^B"). Default is '(f12.2)'. |
---|
131 | |
---|
132 | /POT_ONLY -> Will return only the "power of 10" part of the |
---|
133 | string (i.e. the "10^B"). Default is to return |
---|
134 | the entire string (e.g. "A x 10^B" ) |
---|
135 | |
---|
136 | /MANTISSA_ONLY -> return only mantissa of the string |
---|
137 | |
---|
138 | /SHORT -> return 10^0 as '1' and 10^1 as '10' |
---|
139 | |
---|
140 | /TRIM -> don't insert blanks (i.e. return Ax10^B) |
---|
141 | |
---|
142 | OUTPUTS: |
---|
143 | None |
---|
144 | |
---|
145 | SUBROUTINES: |
---|
146 | None |
---|
147 | |
---|
148 | REQUIREMENTS: |
---|
149 | None |
---|
150 | |
---|
151 | NOTES: |
---|
152 | This function does not "evaluate" the format statement thoroughly |
---|
153 | which can result in somewhat quirky strings. Example: |
---|
154 | print,strsci(-9.999) results in -10.0x10^0 instead of -1.0x10^1. |
---|
155 | |
---|
156 | Need a better symbol than the 'x' for the multiplier... |
---|
157 | |
---|
158 | EXAMPLE: |
---|
159 | Result = STRSCI( 2000000, format='(i1)' ) |
---|
160 | print, result |
---|
161 | ; 6 |
---|
162 | ; prints 2 x 10!u6!n, which gets plotted as 2 x 10 |
---|
163 | |
---|
164 | Result = STRSCI( -0.0001 ) |
---|
165 | print, result |
---|
166 | ; 4 |
---|
167 | ; prints -1.00 x 10!u-4!n, which gets plotted as 1.00 x 10 |
---|
168 | |
---|
169 | Result = STRSCI( 0d0, format='(f13.8)' ) |
---|
170 | print, result |
---|
171 | ; |
---|
172 | ; prints, 0.00000000 |
---|

---|
175 | MODIFICATION HISTORY: |
---|
176 | bmy, 28 May 1998: VERSION 1.00 B |
---|
177 | - now returns string of the form A x 10 |
---|
178 | mgs, 29 May 1998: |
---|
179 | - bug fix: now allows negative numbers |
---|
180 | - keyword MANTISSA_ONLY added |
---|
181 | - default format changed to f12.2 |
---|
182 | bmy, 02 Jun 1998: |
---|
183 | - renamed to STRSCI ("STRing SCIentific notation"), |
---|
184 | mgs, 03 Jun 1998: |
---|
185 | - added TRIM keyword |
---|
186 | mgs, 22 Sep 1998: |
---|
187 | - added SHORT keyword |
---|
188 | - modified handling of TRIM keyword |
---|
189 | mgs, 24 Sep 1998: |
---|
190 | - bug fix with SHORT flag |
---|
191 | bmy & mgs, 02 Jun 1999: |
---|
192 | - now can handle DATA=0.0 correctly |
---|
193 | - updated comments |
---|
194 | mgs, 03 Jun 1999: |
---|
195 | - can now also handle values lt 1 ;-) |
---|
196 | - and doesn't choke on arrays |
