VS2012中调用类似fabs()和sqrt()函数,参数为double类型数函数有效,参数为变量或者复杂的数学表达式无效
调试的时候一遇到这类数学函数都会有如下提示：（以sqrt函数为例）
You need to find sqrt.asm to view the source for the current call stack frame
Try one of the following options:
-Browse and find sqrt.am...
You can view disassembly in the Disassembly window. To always view disassembly for missing source files,change the setting in the Option dialog.

The debug source files settings for the active solution indicate that the debugger will not ask the user to find the file: f:\dd\vctools\crt_bld\SELF_X86\crt\prebuild\tran\i386\sqrt.asm.
The debugger could not locate the source file 'f:\dd\vctools\crt_bld\SELF_X86\crt\prebuild\tran\i386\sqrt.asm'.
没有人回答吗?只有小白我在做数值计算时碰到这种问题吗?求大神解救.

Answer 1

你把你的整型变量或者表达式乘以1.0,然后作为sqrt的参数,这样就可以了.
你没有sqrt的源程序,是无法对sqrt进行调试的.
