◆ SkStrAppendS32()

char* SkStrAppendS32 ( char  buffer[],
int32_t   
)

◆ SkStrAppendS64()

char* SkStrAppendS64 ( char  buffer[],
int64_t  ,

)

◆ SkStrAppendScalar()

char* SkStrAppendScalar ( char  buffer[],
SkScalar   
)

Write the scalar in decimal format into buffer, and return a pointer to the next char after the last one written.

Note: a terminating 0 is not written into buffer, which must be at least kSkStrAppendScalar_MaxSize. Thus if the caller wants to add a 0 at the end, buffer must be at least kSkStrAppendScalar_MaxSize + 1 bytes large.

Floats have at most 8 significant digits, so we limit our g to that.

However, the total string could be 15 characters: -1.2345678e-005

In theory we should only expect up to 2 digits for the exponent, but on some platforms we have seen 3 (as in the example above).
