C51: 64-BIT FLOATING-POINT OPERATIONS

Information in this article applies to:

• C51 Version 5.50 and Later

QUESTION

Does the Keil C Compiler for the 8051 support 64-bit double floating-point operations?

ANSWER

No. The Keil compiler does not support 64-bit floating-point math. You may use the double data type, but operations are performed using 32 bits.

Micro Digital has taken over distribution of the US Software GoFast floating-point library that does support 64-bit operations.

MORE INFORMATION

• Refer to Floating-point Numbers in the Cx51 User's Guide.
