This COBOL system provides IEEE floating-point support. This is fully compatible with the various languages supplied by Microsoft, including Microsoft Visual C++ V6.0.
Floating-point values must be in the range:
For COMP-1 data, | 8.43E-37 | through | 3.37E38 |
-8.43E-37 | through | -3.37E38 |
For COMP-2 data, | 4.19E-307 | through | 1.67E308 |
-4.19E-307 | through | -1.67E308 |
Note that although the above ranges are supported internally, this COBOL system supports only 2 digit exponents, and the range is effectively:
For COMP-2 data, | 4.19E-99 | through | 1.67E99 |
-4.19E-99 | through | -1.67E99 |
The accuracy of floating-point values is:
For COMP-1 data (4 bytes) | 6-7 significant digits |
For COMP-2 data (8 bytes) | 15-16 significant digits |
